On July 8, 1957 KH6UK worked W6LNZ on 144 mhz. For the First Hawaii to California 144 mhz contact. I have always thought this one of the greatest vhf contacts of all time. However, we must note that
Power on the ts2000X can be set for each vhf band and hf by menu. I ran a DEMI xvtr for 222 on the hf side, and SSB xvtr for 903 off 144 and 432 and 1296 direct during the uhf contest. The freq reado
I've often thought a 75 meter (or 40 meter) frequency would make sense for rover announcements and it would not violate the "non amateur" rule. 73 Paul AA4ZZ In examining how I did in the recently co
Perhaps this change would be a good time to review the General Rules and see if some of them should be altered for VHF. It seems that often the issues that arise are with the general rules not the?VH
Gene I use the Demi 222 xvtr at our station. I think that it has the hottest rcv of anything we run. We have just started using the TS2000 with it. I use the 2000?with the hf xmit power turned down t
I operated the 10 Meter Contest several times from a mountaintop with a 4 or 5 element yagi on short (18' or so) tower. One day I felt that the antenna was not operating as it should. I then realized
Path loss is not constant but varies greatly with?weather conditions. Such a program likely assumes a loss number that is good for almost all the time. Whereas vhf contesters work new grids by findin
My best "vhf antenna analyzer" is a Kenwood TF6A triband (144,222,432) handheld with an Air Force surplus Bird wattmeter that is older than I am. A old beat up 5 watt slug and a few coax cables compl
VQLOG (vqlog.com) was designed by a vhfer and has nice grid maps. 73 Paul AA4ZZ I'm a big fan of "Rover Log" for contests, but also want to keep a general log for the shack that will help me track pr
Is this a fixed or portable station? That greatly changes some of the tradeoffs in ease of set up vs. flexibility and performance. Paul <http://user.mc.net/%7Edwhaley>I have decided to run my VHF con

Look of the AA4ZZ team in the ARRL JUne VHF contest this weekend. We will be operating from our mountain top site new Boone NC EM96. We will have 1KW and stacked beams on 50,144,222 and 432. 73 Paul
While 6 meter sporadic E will no doubt have the most impact on the June 2008 scores, it's hard to beat the excitement we had at the AA4ZZ contest?team from the 144 mhz sporadic E contacts with Colora
One solution I have used with my Icom 751A driving transverters is to operate split with the transmit VFO on CW and the receive one on USB. You then just need to learn what the appropriate frequency

David I'm not sure that a stack of loops at 17"? on 432 takes up?a whole lot more space than an egg beater is space is your limiting factor. The Par loops are more easily side mounted on a tower than
How about GriDXpedition as shorthand for Grid Expedition. 73 Paul AA4ZZ? I'd like to coin the term "GXpedition" or "Grid Expedition". As a Rover, I've made one or two of those... I like the idea of a
