Paragraph 2: cluster information

Q2-1: What is cluster.dk?
A: Cluster.dk is a notification system for 11-meter DX radio communication. Via this system you can be notified about DX – and you can notify all your friends when you listen/work something interesting heard "on air".
You can be notified via internet and via e-mail (/SMS). The e-mail (/SMS) notification part offers you an innovative filter system. Via this filter-system, you can set up your own reception profile based on DXCC’s, so the cluster will only e-mail (/SMS) you the spots, that you are interested in receiving.
In this way you only receive mails/spots, when the DXCC's you are interested in are reported.
You can see all new spots via the Spot Board. This board is automatically updated for every new spot made.



Q2-2: Is cluster.dk a mailinglist like many other lists?
A: No, cluster.dk is not a mailing list!!
cluster.dk is a full and complete datasystem - and controlled via internet.

Every single user can - in fact has to - control all personal settings him/herself. This is done via internet. To change settings, please log in to cluster.dk and click "Change user info".
Read this FAQ to learn all about what can be controlled and how this is done.

More info about cluster.dk versus a mailing list:
Mailing lists offer you one (1) list: either you receive the e-mails, or you don't receive the e-mails. At cluster.dk you can preselect which mails (spots) you want to receive within 250,000 different combinations.
Another difference is that when you want to make a report (send a spot) at cluster.dk you have to fill out a special page (the "Report new spot"-page). You cannot send spots/reports via e-mail.



Q2-3: How do I subscribe to cluster.dk?
A: Go to http://cluster.dk (click "Home")
- click at "new user"
- follow the wizard and
- wait while your profile is being validated (normally max. 24 hours), and ...
- bingo - you are subscribed. Congratulations and welcome.



Q2-4: Is this service really free of charge?
A: Yes - for you. Please also see next question :-)



Q2-5: How can I support cluster.dk?
A: The best way you can support cluster.dk is by joining cluster.dk Lounge. This gives a good support to cluster.dk so we can maintain cluster.dk system - and besides this we try to offer you (as a Lounge member) even better service:
"When you support cluster.dk in a special way - cluster.dk supports you in a special way."
To learn all about cluster.dk Lounge, please read all information at our Loungepage here.

Besides joining cluster.dk Lounge, you are welcome to support cluster.dk in other ways. Feel free to donate a free contribution to cluster.dk. Our address is:
cluster.dk
P.O. Box 77
DK-4840 Norre Alslev
Denmark Europe
- or contact administrator for further information. Thanks.



Q2-6: Soren - why have you made cluster.dk?
A: Because I'm dedicated to 11-meters.



Q2-7: Is cluster.dk the worlds most visited 11-meter DX site?
A: Probably - yes.



Q2-8: Why are my new profiles rejected? I have tried again and again...
A: There can be many reasons for us to reject your new profile:
- you already have a profile. We only allow you to have one (1) profile at cluster.dk
- you have filled in the required information incorrectly, for instance used a callsign that is not according to our Rules for using cluster.dk callsigns
- you are making (what we believe is) a fake profile
- The information you have given is not true, not valid, false, or similar
- you have given us e-mail addresses that are non-valid/non-working
If we reject your profile and you do not understand this, please contact the administrator for information.



Q2-9: Do I have to send spots to the cluster?
A: YES.
If we all just sit and wait for "the goodies", no spots will be sent at all. If we all send spots from time to time - or better: more often - there are a lot of spots circulating on the system, and the more spots, the bigger are the chances for YOU to receive exactly those spots, YOU are waiting for. And for everyone using the system. So, this is a benefit to everyone.

Q3-14: Why is my profile suddenly inactive?
A: If your e-mail addresses are bouncing (e-mail sent to you is returned by your internet provider as a result of problems with your mailbox), we immidiately discontinue all e-mail to that address. This is done by de-activating your profile.
If your profile suddenly is in-active, please do the following:
- check that your mail inbox/SMS inbox is empty and can receive mail
- check that your internet provider has no problems with mail
- go to cluster.dk and activate the profile - as described in Q3-3
If e-mail to you is discontinued several times within some few weeks, please contact your provider.

If problems continue we will disable your profile in such a way that the profile can not be used (until all problems are 100% resolved). Please read Q3-18 for more info.



Q3-15: Why are some users callsign purple?
A: cluster.dk has a team of 8-10 Supervisors, constantly monitoring the system. These Supervisors are posting to the Message Board with another colour - so you can easily identify them, and so you know that they are present.
Please do exactly as the Supervisors instruct you.
The Supervisors are instructed to report all incidents to Admin.



Q3-16: What is a Supervisor?
A: A Supervisor is a special cluster.dk user - appointed by Admin. cluster.dk has a team of 8-10 Supervisors, constantly monitoring the system. These Supervisors are posting to the Message Board with another colour - so you can easily identify them, and so you know that they are present.
Please do exactly as the Supervisors instruct you.
The Supervisors are instructed to report all incidents to Admin.



Q3-17: What is the difference between "active"/"in-active" and "enable"/"disable"?
A: This is very simple:
- "enable"/"disable" is used to enable/disable the entire profile.
- "active"/"de-active" is used to activate/de-activate your reception of spots via mail.
When the profile is disbled, the profile cannot be used.
When the profile is enabled, you can decide if you want to receive spots or not. If you want to receive spots: activate the profile - if you do not want to receive spots: de-activate the profile.



Q3-18: Why is my profile suddenly disabled?
A: First - Please read Q3-14.

Hi administrator,
I have forgotten my userid. Please send me my userid. Thanks.
My callsign is: xxx and I also use the callsign xxx.
I use these e-mail addresses: xxx@yyy.qq
Thanks



Q4-3: I am subscribed, but I do not receive any spots?
A: Please check to make sure the e-mail address you used to receive spots is working by sending an e-mail to yourself. Do you receive the e-mail?

Q4-4: From time to time you send out a special mail regarding bouncing mail. Why?
A: From time to time we send an e-mail, in order to test bouncing e-mail addresses. When you receive this e-mail, please just delete the e-mail. Do not return the mail to cluster.dk administrator.
In case you do NOT receive the mail, the reason is, that you have problems with your e-mail address. In this case the mail is returned (bounced) back to cluster.dk administrator, included your QRZ in top of mail. Then administrator can de-activate / disable the profile, so further bounces are minimized.
So, when you receive this special test e-mail from Administrator, please just delete the mail and do nothing! Thanks.



Q4-5: Can I send my spots as e-mail to spots@cluster.dk:
A: No. You can only post spots via the "Report new spot" page.



Q4-6: I want to change the DXCC's in the source or destination list. How do I select only a few DXCC's?

- to untick one DXCC: Press control (ctrl) and untick



Q4-7: Why do I have to write to the Administrator and Webmaster in the English language?

Q4-8: I do not receive spots as e-mails to my home e-mail address anymore, why?
A: There could be many reasons for not receiving spots. Before writting to Administrator, please check the following:
* Does your e-mail address receive other e-mail? (If no, please fix this problem first)
* Have you made changes in the setup of your PC recently? (If yes, please check the complete setup of your PC, as the problems are probably local to your PC.)
* Do you use a Firewall (ZoneAlarm etc.)? If so, disable/de-activate the firewall and see if things then work correctly.
* Did you make a spotmail-test from cluster.dk Test Center? (If the mail is not received, please solve this problem first.)

* Please go to cluster.dk and check your profiles setup:
- The profile must be "enabled" and "active"
- The filter-settings must be in a way, that you should receive spots
- the e-mail addresses must be 100% valid and working

Go to the MessageBoard and - if possible - find other users from your own country. Does it work for them? (If not, please wait 12 hours and see if problems will be solved in other ways.)

If all the above is OK, please write to administrator.



Q4-9: I do not receive spots as e-mails to my Hotmail/Yahoo mailaccount anymore, why?
A: There could be many reasons for not receiving spots. Before writing to the Administrator, please check the following:

* Is your mail inbox empty? (if not, please delete all e-mails in your inbox)
* Did you make a spotmail-test from cluster.dk Test Center? (If the mail is not received, please solve this problem first.)

* Please go to cluster.dk and check your profiles setup:
- The profile must be "enabled" and "active"
- The filter-settings must be set in such a way, that you will receive spots
- the e-mail addresses must be 100% valid and working properly



Q4-10: I do not receive spots as SMS to my mobile phone anymore, why?
A: There could be many reasons for not receiving spots. Before writing to Administrator, please check the following:

* Is your SMS-inbox at your mobile phone empty? (if not, please delete all SMS messages in your inbox).

Q4-11: I want to receive spots as SMS to my mobile telephone. How do I do that?
A: cluster.dk offer all users to receive the made spots as e-mail - LIVE.
Normally spots will be received by your e-mail-provider less than 60 seconds after the spot is made.
We do not use a SMS gateway, and we therefore can not send you the spots as "true SMS", however most mobile providers offer their costumers e-mails as SMS. Please contact your mobile provider for more information!!
(Most providers uses the address system "telephone number@provoder.xx" - example: 123456789@vodaphone.it).

Paragraph 5: How do I make a spot?

Q5-1: I want to send spot/reports via e-mail - how do I do that?
A: All reports must be made via Internet - http://cluster.dk - "Report new spot".
You cannot send spots/reports via e-mail!



Q5-2: How can I make a testspot?
A: Do not make testspots.
It is absolutely prohibited to make testspots at cluster.dk. If you want to test your own e-mail address (home e-mail adress or mobile GSM), then send an e-mail from yourself to the e-mail address. You're also welcome to use our Test Center.
To find the Test Center:
- click on "Report new spot"
- click on "Test spot"



Q5-3: How do I fill out the "Report new spot"-page?
A: Please fill out the fields with as accurate information as is possible - remember, you make a spot to help other friends work this specific station. Fill out the fields as explained below.
Only make spots, when the information is 100% valid and can be used by other users of cluster.dk.
Please make the spots as soon as possible - the sooner the spots are made, the greater the chance that other users will have an opportunity to work the spotted station also.
A spot made after the spotted station has left the frequency is not much help to other members.

Fill in information at "Report new spot"-page as follows:
- Line 1: Everything is filled out for you (prefilled). You can refresh date/time, if you have been on the page for more than 1 minute.
- Line 2:
"To DXCC" : Write the DXCC you are reporting (for example 47). Do not write your own DXCC.
"Frequency" : Write the frequency used. You must write the correct frequency used. Insert the frequency in kHz without dots (example: 27650).
"Mode" : Select the the mode type.
"QRZ" : Write the QRZ (callsign) of the reported station. Only write QRZ, no operator name. Please use the defined standard for QRZ (callsigns), as seen at "Report new spot"-page" and cluster.dk Rules-page.
"Worked" : Use the terms as described here:
* Worked: use Worked when you actually have worked the reported station
* SWL: use SWL when you heard the reported station - but did not have a QSO-with him
* NIL: use NIL when you cannot hear the reported station, but you know for sure, that the station is active on the specific frequency at the moment. This is to let other users and friends know, that the reported station is active right now at the reported frequency.
"Comments" : Use the comment field for relevant information only. See the comment field's help-text (at "Report new spot"-page) for further information.



Q5-4: Why do I have to report a station in your way ("47LD101")? I spoke to xy01, and the xy-group does not support the DXCC-system.
A: If we do not use the same system all the time, we cannot use the search facilities in the Archive, the Activations Database and Managers Database in the fastest, best and most efficient way.



Q5-5: Why do I have to report a station in your way (47LD/DX)? I want to write 47ld-dx.
A: Because if we do not use the same system all the time, we cannot use the search facilities in the Archive, the Activations Database in the fastest, best and most efficient way.



Q5-6: Should I report a station at "call frequencies" (26.315 + 27.555)?
A: In general, please do not spot stations at the call frequencies. Instead listen for their QSY-frequency and report this frequency instead.
Please notice: The reason for making spots are to alert your friends - and all other users - about a specific station "on air" NOW, in order to give other users a chance to work the same station before this station closes down the radio, or changes frequency.
Therefore is it much better to find the QSY-frequency...

There might be situations where a rare station is active, calling CQ at 27.555 without giving a QSY-frequency ! In those situations, of course spot with frequency 27.555.



Q5-7: When do I click "Send report", when do I click "Send report to web only"?
A: When you have filled in all information at "Report new spot"-page, you must make a decision:
- will you send report to the "Spot Board" only? OR
- will you send report to the "Spot Board" AND send the report to all cluster-users via mail (according to filtersettings, active/inactive etc.)

When you are reporting stations that have been reported short time ago, or the DXCC is not especially "interesting" compared to how many active operators there are living in the DXCC, how often it is activated etc., then click "Send report to web only (not to mail) only.
When you feel your spot will be extra interesting to other users then click "Send report", Thanks.

For every spot made, always consider:
- is this in general interesting for other users of cluster.dk? If so, send the spot to Spot Board only.
- is the spotted station more interesting than average? Or are there other special reasons for notifying thousands of users via mail/SMS? If so, send the spot also with notifications (=click "Send report")...



Q5-8: Why type in a Signal and Radio report?
A: Giving an accurate signal and radio report in the comment section of a spot can give a good indication to other cluster.dk users what propagation is like to that particular DXCC from the source country of the spot.

cluster.dk uses parts of the "RST system" - used on HAM-bands. This system is mainly used on the 11-meter band, and when we all use the same system we avoid misunderstandings when giving a report.

Some operators also use the phrases "Radio report", "Signal report" or "Readability and Signal report", always covering both R/S.

The system always used R/S (Readability/Signal strength) - and not S/R.

A report is always written like this: 5/2, 5/9, 5/5, 4/2 etc.



Q5-9: How do I give a correct R/S report?
A: Most operators will give and receive a Readability and Signal report (R/S) in just about every QSO made, so it is important to give them correctly.
An accurate signal and radio report will give a good indication of propagation, equipment performance as well as other things.

Example of a radio report:
"a 5/7 report" = Readability 5 and Signal Strength of 7, that indicates that the received audio is perfectly readable with a moderately strong signal, please see the chart below:

READABILITY
1 - Unreadable.
2 - Barely readable, occasional words distinguishable.
3 - Readable with considerable difficulty.
4 - Readable with practically no difficulty.
5 - Perfectly readable.

SIGNAL STRENGTH
1 - Faint signals, barely perceptible.
2 - Very weak signals.
3 - Weak signals.
4 - Fair signals.
5 - Fairly good signals.
6 - Good signals.
7 - Moderately strong signals.
8 - Strong signals.
9 - Extremely strong signals.


Looking at the chart in detail, it is noticeable that there is not a Readability or Signal Strength of 0 (zero), so theoretically a radio report which includes a zero is incorrect!
- 3/0 = incorrect
- 0/1 = incorrect
- 5/0 = incorrect

Some operators rely too much on their transceiver signal strength meters. If you can perfectly hear a station but there is no defection on the transceiver signal meter, a radio report of 5/0 is incorrect, as 0 indicates no signal at all. A report of 5/2 would be considered an accurate radio and signal report, because this indicates a perfectly readable audio with a very weak signal.

Please be honest in your reporting, do not just give everyone 5/9. People want to know as you do what their report really is. And other people trying to contact them want to know if the signal is strong or weak.



Q5-10: Why shall all spots include a DXCC-number?
Because else we cannot send spots via notifications/emails.
More explanation:
cluster.dk offer all users to receive spots via smart phone (and email) notifications.
In this way you can be notified about interesting stations "on air" right now - information sent directly to your smart phone (or via email) the same second that the spot is made.
But you dont have to receive hundreds or thousands of notifications every day: You can setup your own personal filter system in the settings section: "Change user info".
In this way you are only notified when (for you) an interesting DXCC is spotted.

Select between nearly 125.000 different filter settings: Choose which DXCCs sender should live in - and which the spotted station should live in - and receive notifications only when the spot made matches your filter settings.
cluster.dk users produce more than 500 spots every day on average - and some days more than 2.000 spots. Because of the filter system you will be notified only when your favourite DXCCs are reported.

To access the filter system:
- click "Change user info"
- click "Filter Settings"

cluster.dk filter system is based at the DXCCs inserted into the spots made. Therefore all spots must include a DXCC-number !!!
If callsigns "on air" do not include a DXCC-number, please search for the DXCC-number or Entity (ask the operator) or use DXCC-number 700 when sending the spot. Gladly, the majority of clubs and operators do support DXCC-numbers, and due to this you can receive a notification when (for YOU) a nice DXCC is spotted - and then work yet another new DXCC.

Paragraph 6: Filter options

Q6-1: I receive too many spots every day - help me, please!
A: Use the filter.



Q6-2: What is "The innovative filter system"?
A: At cluster.dk, you don't have to receive a lot of e-mails, concerning DXCC's you are not interested in. If you have worked all DXCC's in the Pacific and now don't want to receive spots regarding the Pacific, you use the filter to stop those e-mails from being sent to you.
If you don't want to receive spots sent from "the other side of the world" (if you live in New Zealand) and therefore don't want to recieve spots sent from Europe, you use the filter to stop those e-mails being sent to you. It is very easy - and only found at cluster.dk.



Q6-3: What is "the filter"?
A: The filter is made for users that want to receive spots via e-mail or SMS, but don't want to receive ALL spots posted at cluster.dk. When using the filter, you receive fewer e-mails and e-mails specific to your choosing.

When a station in Spain is reporting a station in Australia, we talk about Spain as a "Source" DXCC and Australia as a "Destination" DXCC.
You can select exactly the DXCC's you wish as "Source" and as "Destination". Combine these combinations and you have more than 100,000 different possible settings.

The easiest way to explain about the filter is via examples:

Example 1: You live in Australia and are receiving too many spots that are worthless to you.
A: You only want to receive spots when they are posted from Australia, New Zealand, Japan and surrounding DXCC's.
=> Select only 43, 41, 25 (and other "close by" countries) as "Source" and select all distant DXCC's as "Destination".

B: You only want to receive spots, if the DXCC is a "Bingo - new one" for you:
=> Select all DXCC's in "Source" and select only your few missing personal DXCC's as "Destination"

Example 2: You live in South Europe and are receiving too many spots that are worthless to you.
A: You only want to receive spots which are "new or interesting" DXCC's.
=> Select all DXCC's in "Source" and select only your personal interesting DXCC's in "Destination"

B: You only want to receive spots, when they are sent from your own DXCC:
=> Select your own DXCC in "Source" and select all DXCC's as "Destination".

Example 3: You live in the USA and are receiving too many spots that are worthless to you.
A: you only want to receive spots when they are sent from your friends in The States.
=> Select USA (DXCC #2) in "Source" and select all DXCC's as "Destination".

B: You only want to receive spots, when they are sent from South America, Central America or North America:
=> Select the following DXCC’s in "Source": 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 etc. (All prefixes from South America, Central America and North America) and select all DXCC's as "Destination".

Example 4: You live in the South Cook Islands, and are receiving too many spots that are worthless to you.
A: You ONLY want to receive spots, when YOU are reported:
=> Select ALL DXCC’s in “source” and select only DXCC 250 in “destination”.

B: You only want to receive spots, when the spots are interesting to you.
=> Select the DXCC’s in “source”, you want to receive spots from (Pacific region). Select the DXCC’s you still haven’t worked in “destination”. Now you only receive spots, if they are sent from a station in Pacific, and the reported station is on your “wanted list”.



Q6-4: I want to use cluster.dk, but I do not want to receive spots at all !
A: No problem.
De-active your profile:
- Click "Change user info"
- Un-tick "Active profile".
- Click "Save profile changes".
Now you have an enabled profile - however you have disabled reception of spots to you.

- managers name
- managers full address
- the callsign/callsigns of the activations the manager is managing.

Q8-6: I have problems sending spots - what is wrong?
A: In the case where you see other users are making spots - the problems are probably not at cluster.dk.
Many things may be wrong - problems are likely related to your PC's setup, the sofware or hardware used- or your ISP.
- first - try to delete all "temporary internet files" from your browser. Did this solve the problem?
- did you install any new software lately? (i.g. a personal firewall or other kinds of security software)?
- did you make any changes to your browsers setup?
- do you have other PC's at your home? Are the problems the same on these PC's?

(Without guarantees at all, this can be necessary:)
- try to remove the browser software and install it again.
If problems continue, Feel free to contact administrator.



Q8-7: The Main Page (Spot Board) does not refresh? What can I do?
A: Problems like this are typically related to problems with your PC's setup, the sofware or hardware used- or your ISP.
When this kind of problem is presented to the Admin, we always recommend that users - first - delete all "temporary internet files" from the browser. Often this solves the problems.
If not, please read Q8-6 for further assistance.



Q8-8: The Main Page is suddenly strange (without normal colours) - What then?
A: We have seen this problem a few times - it seems to be related to your ISP.
Always try to delete all "temporary internet files" from the browser.
If problems continue for more than 10 days, feel free to contact administrator.
