Not sure what to say? I double checked all the solder joints on the connections and touched up any that seemed to be at all suspect. Using the schematic for the front panel board traces I made a

I assume it powers up and down properly using the top knob, but draws 200 ma. So the processor is working, but not yet convinced that the power supplies working. If you look at LIN_REG_EN on the first

Most likely that the wires of L403 are not soldered properly. No need to rebuild it. Add some flux if you have it, heat each of the 3 wires of L403 with a soldering iron till the solder melts, then

Jerry, Sounds like a “cheap Chinese clone” in the making!

Still have my HP35 from college, it's an old friend. Battery pack has long since dried up and died, keys show a decade of heavy wear, power supply cord patched where it enters the wall wart.. But

I do wonder how much interest there is in 160m and 6m. Reducing coverage to the traditional 80-10m makes room to use a cheaper 4 layer board, perhaps even with all surface mount parts on the bottom,

Double check the solder connections on all of the through pins that connect the display to the board with the front controls (not sure what it is called, but the board with the encoders, buttons, mic,

When in the mode the aim is to get the LED to be unlit. Due to the way the transmatch works it will not show 1:1 (or close to) on the radio. When you switch it out of tune mode it'll then show 1:1ish

Wonder if K46 actually gets released this month... 73 -- Matt N3AR

I have bought a couple of K42s, first one without backlit and I spent some time retrofitting it (display was not so common). Luckily I was able to make Steve change his mind about it and he eventually

Hi, I recently got my cute little QMX. While I'm going to learn to operate it and learn CW (not yet ready for letting it out in the wild), I thought I'd try WSPR first. The SW (FW rev 24 [*]) lets me

Hi all might agree, The World needs a QMX all band receiver only product. much cheaper, maybe all smd, maybe Hans can fit a 18650 or 14500 Li-ion battery inside vs 73 DE muhsin, TA1MHS

Hi Hans please please extend the Band configuration of the QDX first so we can 40-30-20-17-15-12-11-10 properly (using the QMX+'s LPFs and BPFs filter schemes on those bands) (with T-30 toroids) 73 DE

Bruce, I was going to recommend a 12V build. Another option is the Smart Power Attenuator from WA2T. This allows adjustable attenuation from 1-15db, and it saves settings for each band, and changes
