Re: Chinese Pixie Part II
Looks like you saw many of the same things I did during the build. http://kc9on.com/ham-radio/chinese-qrp-kits/
One thing I can't check was the output. Would be interesting to see if a LPF is needed and what harmonics are coming out.
The A/C noise is terrible with a 35+ year old power supply but moving to a battery solved that problem. Also no dice with FLDigi decoding in the daytime and ended up using an audio filter to remove the highs. Can't complain after making a 280 miles QSO with it. What more fun can you have for $7 now days?
I was disappointed in the Frog, definitely not the power out as claimed but with a simple cut and wire turned the RF gain pot into a RIT control. Rockmite (non-PIC) version is nice but ended up jumpering out the CPU and fixed the audio "squeal" issue. Want to try the newer Rockmite (w/ PIC) and see if it's any better.
The Chinese 49-er and tuner kits arrived in the mail yesterday. Now just need to catch up at catching up and I can build/play with those also!
