i've been playing with NorCal40 qrp rig for 40 meters, serial #2.
drain on receive measured at 14mA (that's 14 milliamperes).
drift at 65 degrees F from cold start:
0 min 2.124504MHz on VFO
1 min 2.124520MHz
2 min 2.124528MHz
3 min 2.124528MHz
5 min 2.124528MHz
10 min 2.124528MHz
30 min 2.124528MHz
so, i measure the total drift at 24Hz. i would not have believed it
possible with a varactor tuned VFO, had i not measured it myself.
this was done with a Heath 200MHz counter calibrated with WWV.
i did it again, but got only 15Hz. i'll do it again monday nite.
i figure that i had affected the results of the second by doing the
first and had allowed only 30 minutes for cooldown. i'll let it sit
for 24 hrs and try again.
i haven't gotten to receiver sensitivity yet or transmitter.
i now have a spectrum analyzer and have to check it out and
then measure a few rigs to see how they are doing.
stay tuned to your bat channel, same time same station......

p.s. i didn't get on this weekend. the kid up from college for
the weekend and took him and the wife out for dinner and a movie.
and thank you people up north for the cool weather. really appreciate it.
