ARLA/CLUSTER : RE: [HFpack] VHF intercom freq 144.300 Re: Mobile HF/VHF to DaytonHamvention

[Miguel Andrade]

Hello everybody,

With all respect let me inform you that here in Europe ( and at IARU Region
1 in general ), we use the frequency 144,300 MHz just on SSB for
international DX call.
Please be so kind and take a look at IARU Region 1 VHF/UHF/Microwaves
Bandplans.
In fact, many of us can testify for you an interesting SSB activity at this
side of Atlantic on this segment, ( as well as a few brief clashes from time
to time with some “ FMers “ that don’t know yet the international
procedures ).
I am not talking about contest activity but daily DX contacts in SSB (
please take in consideration several cluster sources like the Dxrobot and
others ).
At this side we do call a lot for long distant contacts in 144,300 MHz ( and
than move quickly above or below for QSO ).
If your activity would take place in North America or any other place in
Region 2 or 3, I believe there is no problem at all, but if will be for a
world wide plan please think about it and consider my information.
Let me wish you all the best and take care.

73’s from Miguel ( CT1ETL )

Assunto: [HFpack] VHF intercom freq 144.300 Re: Mobile HF/VHF to
DaytonHamvention


Hi Chris,

We've discussed the HFpack VHF intercom freq 144.300MHz before.
So far, no one has found a universal frequency
better suited for the purpose. 144.3 is in the only
common segment of 2 meters that is available worldwide for
multi-mode itinerant use.

HFpack is an international group, so the choice of frequencies
are made to benefit all members, and with world travel in mind.
It has been in use successfully for this purpose for many
years without any interference or problems.

The frequency choice criteria was:
1. Available frequency in all countries of the world
2. Low power, used mostly for hamfests, short range rendezvous
3. Available for multi-mode (CW/SSB/FM/Digi/text)
4. Available for Simplex (not a repeater input).

144.3MHz is not an active frequency with present satellites.
144.3MHz is not in a protected beacon segment.

Anyone is welcome to suggest another frequency for future
 consideration which meets the criteria.
