[CQ-Contest] SSB & CW On Same Band

Andy, Thanks for this clarification.  Understood.

 

I still think it is a slippery slope and a mistake, even for the assisted category.  Especially with more and more people calling for merger of unassisted and assisted.

 

>From a practical standpoint, it would seem much more likely that competitive entries wanting to SO2R with clear reception would take advantage of a remote receiver up to 100km away than lot restricted entrants needing it just to get on and compete.  But maybe I am wrong.  Have you been able to collect any info on who is actually taking advantage of the rule?

Hi Ed.

Just to clarify about the CQ 160 contest;

The option for remote receivers is available ONLY in SO Assisted category.

It is not permitted in Single Op or Multi Op.

It's inclusion was in direct response to the request of more than a few participants.

Due to the unique nature of 160, and lot limitations; many have added that capability.

They have high noise levels at the TX site.

This accommodation was made to mirror the same rule incorporated in the Stew Perry contest.

Remote RX must be located within 100KM of the TX site.

 

 

There have been some abuses of this, but due to the tools we have now it is easier to detect.

As always, we hope and expect all contestants to follow the rules.

73, Andy N2NT

Some of the SO2R operators run 2 radios on one band and I believe MOST of
the mult-ops do.



I do here at N1UR.  I use cross polarization (transmit vertically on 160 and
listen horizontally - and transmit horizontally on the other bands and
listen vertically).  I also use tip to tip orientation and at least 300 ft
separation.  Using Low Power, I had pretty much the noise floor to within
20khz on all bands - 10khz on CW.



With high power, the noise floor is lifted by probably 20dB across the band
but otherwise everything is totally readable to about 20 - 25khz from the
signal.



I run the 2nd receive signal always through the aux receive port and through
a front end protector.



It takes good engineering and the space to place things in the right part
and with separation.  But its doable.



Hopefully such required engineering practice doesn't get killed by the
ability to operate remote receivers in the major contests.  I was not happy
when that option was given in the 160 CQ WW contests.  A bad decision in my
opinion.
