Re: Greetings from K7TP - Norcal Tuner - and a Request for Help
- Grover :
After seeing your pictures I now regret selling my St Louis Tuner kit years ago.
It makes a nice companion for the Sierra.
Good luck with you 17m module.

Played with Sierra #3 - the Wilderness version this afternoon, unsuccessfully.
I have solar power panels installed on the roof, and the S9 hash and spikes (every 30khz)
kill any idea of operating during the day.
As I have so many lipo battery packs from model aircraft use, I use the 3S ones
that give out 11,1 volts. These I have in a variety of sizes from 800mah to 3300mah.
Tried a 2S pack (8000mah) at 7.4 volts and Rx was little different (for what it was worth
with the hash) and power on Tx was down a bit, but it still surprised me that it worked OK.
THUS - does anybody know what the minimum operating voltage of the rig ????
(No - I don't have a variable power supply to find out for myself).
I still have to assemble the extra modules for my trip to Tasmania later in the year.
I will be using a 30' squid pole with a slinky loading coil for the antenna. This to use
while camping out near streams as I attempt to catch a few rainbow trout.
