[Lowfer] Testing 74.321.5 tonight QRSS 60

[Pat Bunn]

I drive my transmitter with a gps disciplined HP signal generator so I can move around easily. I picked that frequency pretty much at random since you guys  were not transmitting tonight. 

I have had a lot of trouble getting the vertical antenna to load up properly. It loads up fine on 137 but 74 KHz has been a problem. I am using a scope match but I don't seem to get a high Q resonant match that I would expect. Still have some more work to do. Looking at my signal tonight, I am getting only 35 watts or so and the amp is running very inefficiently yet it works great into a dummy load. Not sure what is going on as it seems to be running cool. Reading the power with a calibrated scope and assuming 50 ohms at the output of the filter.

> Glad to see your about to come on 74.  I have been using 74.3213 so you might be a bit close.  Dex uses 74.322  You might plan on going up a tad or down  is good too.  I am planning to spark up tomorrow night there as the return to cold weather could give some good results-Bob WG2XRS/4 NY
