Subject: [4SQRP] Cricket & antenna experiment
I haven't had much luck making Cricket QSO's with my multiband 80m
inverted V dipole, so early this morning I decided to try the wire I use
for shortwave listening. It's about 120' long with a lead-in wire
attached about 10' from the near end coming down to a 9:1 balun in a
plastic box mounted on the side of the garage, then coaxial cable over
to the house and into the shack. I was surprised to find that the wire
has a near perfect VSWR on 3560 and 3580. I gave a few CQ calls and was
happy to see that I was actually being heard on the reverse beacon
network for the first time with the Cricket.
I had always been leery about trying to transmit into this antenna since
I just used 24 gauge magnet wire to build the balun and am not sure what
kind of power it will take. But 1/2 Watt won't hurt it a bit.
The only bad thing is that I have a loud 60 Hz hum on that antenna with
the Cricket. I don't have the hum on any other receiver, nor do I have
the hum with the Cricket on the V. So I believe it's likely a ground
loop issue. I'll try to work through it until I get the Buzzkill finished.
So tonight I'm going to finally (hopefully!) make my first Cricket QSO.
I plan to be on around 7 PM onward.
