Hi all

On 70 MHz we are in a somewhat unique situation that often split operation has to be used. On direct propagations this is not a big issue. But on random meteor scatter things are different.

Therefore I suggest that we invent and confirm the following CQ split method:

Calling CQ QRG means that the caller till keep on TXIng on the existing QRG but will listen on QRG, e.g.:
- I call "CQ 950" on 70,270. This means I will keep on TXing on 70,270 MHz but will listen on 69,950 MHz
- Someone is calling "CQ 265" on 69,950 MHz. This means that "someone" will keep on TXing on 69,950 MHz but listen for me on 70,265 MHz

This ALSO means that:
- calling CQ where QRG is above 500 refers to 69,qrg MHz.
- the normal CQ QRG QSY principle is not used on 70 MHz.

How say?

OK, I like random much more than skeds I must admit.

An interesting idea.

Many DXCC have access to 70.270MHz = all of UK, OK, OZ, EI, ES, OH, OX, S5, LA, CT, YO, T7.

Notable DXCC that do not have 70.270MHz include EA, I, LX and some others. That's tough! I know where to find DL & ON.

You could adopt three systems.

CQ QRG xxx (to indicate split) or

CQ xxx (to indicate qsy to a common frequency) or

CQ (when traffic is low)

Hi

This is not an issue about 270 as such but split operation.

But to ellaborate on your feed back:
- CQ SQRG = split and RXing on QRG and keeping TX on existing freq.*
- CQ QRG = same meaning as now, i.e. both stations QSY*
- CQ = no QSY

*: 70 MHz special note QRG above 500 means 69,QRG MHz otherwise "same" MHz

Sounds good - just 270 is bit problematic here because 250-300 power is limited 25w and it is FM simplex bandplan area. Also if somebody CQ this direction must remember KP54HQ OIRT 4 kw WFM station what make quite meny "burst" also.

will freq be for all modes? so HSCW/JT6M/ISCAT/FSK441/JTMS/Diana etc?

100% support for this - I would be very pleased to see more random MS activity on 70MHz.

CQ QSY is tried and tested and should fit well here.

Prefix the qsy with S meaning my tx will remain here and I'm listening on the QSY freq. That looks very practical.

As an aditional note - PLEASE listen for follow on QSO's and dont just go scurrying back to KST to line up the next sked.

Hello

During showers and generally good a MS conditions skeds are an effecient way to limit the number of QSL cards to be written.

I think I will make MS page here on the site with the concluded QSY idea.

Thanks!

ciao all
ok for split operation method by OZ2M, but i have a question;
what qrg we can use for random ms cq ???
as 144370 on 2m and 50230 on 6m.

Hi

Is is not easy to assign one specific random frequency for MS due to the fragmented allocations from one country to the next.

However, I think we should implement this bandplan: http://rudius.net/oz2m/70mhz/bandplan.htm

My point was more about the "method" of operation than a specific frequency. Therefore the "method" can take place anywhere all in the favour of more random operation and less chat made, assisted or arranged contacts.

Do we have enought activity to make random MS contest like BCC during Gemidies shower?

edit

rules may copy from there

I don't think there is currently enough random MS activity on 4m to justify a contest but maybe that's a catch 22 thing, if there was a contest maybe it would promote the activity. I for one would definitely be active.

With SDR its easy to find people calling CQ and have real random QSO's but not everyone has this yet and very few people call CQ. None heard at all this last weekend.

Assuming we see a good take up of the proposal here then the activity will breed activity.

During the upcoming showers I will be calling random CQ and hope to see (and hear) some activity.

Hi

Ture random is difficult with the fragmented allocations. But it is not impossible and it is definately possible on an announced frequency. When I call random, from home and not on a DXP, I annouce it on the DX cluster.

MS contest? Hmmm why not. Let me sleep on it. But it is a natural choice for The Four Metres Website to arrange. Furthermore Geminids are soon about.

Sure we dont need 11th 20z - 15th 02z MS contest on 4m but maybe 12 hour or 6 hour sprint around maxim. Hmmm - same idea will be ok also on 6m where can kick band what is quiet now...

Hi

Here is a proposal for a 4 m MS contest: http://70mhz.org/4mmsc.htm

Please feel free to comment.

I'll try and be around for some of the time.
I'm supposed to be working but will try to sort something.

Cheers
