In this case, I just key it in. The band will change to 30-meters and if you
cycle through the bands, the next time you hit 30-meters you will be set to 9
MHz.
BTW, I have my M1-M4 memories set to "default" frequencies for each band so
that M1=CW, M2=SSB, M3=Data A (PSK) and M4=AFSK-A (RTTY).
It should be noted that another "secret" is that sometimes the DX station tunes
his receive frequency with some pattern. So you don't want to be on either his

I'm using a TGE in my station. I originally bought it to use portable while on

Just because the radio puts out rated power at lower voltages doesn't mean the

Actually,
some old International Harvester diesels did have spark plugs. They
started on gasoline and after they warmed up, the operator switched
them over to diesel :-)
Otherwise, this remind
Doug,
It's been a long time since I was on EME and time has marched on to where the
current ops are using digital modes to pull signals from below the noise and
calling them "contacts". But when we actually listened for signals, hours were
spent listening to noise and I can assure you that dist

My charger is actually a marriage of some commercial gear with a few tweaks.
The motivation for this was the absolutely horrible RFI from the switch-mode
charger in my 5th wheel trailer. It was so bad that when I had the trailer
stored here at home the RFI would actually inter

Steve,
Congratulations and welcome.
I can't recommend a manufactured antenna since I make all of my own, which I
encourage you to do eventually. I do understand your desire to get on quickly,
though and I suspect you will get a lot of recommendations, some better than
others.
As to the batt
Congrats James.
I've been homebrewing since 1958 but I too just put together an XG2 that Santa

Sounds like Tokyo Hy-Power in reverse. I now get to pay dealer markup and

Hi Paul,
Well that will certainly depend upon antenna efficiency, but QRO makes the
