I recently purchased a QMX+ kit and soon started following this group. I finished my kit today but I'm having a couple of issues after kit completion and I'm hoping to get some ideas. I've nearly resigned myself to purchasing another kit and starting over due to at least one error I know I've made. The unit powers on and I was able to flash the firmware without trouble. Hardware diagnostics in the terminal look OK.
?
1. When plugging in headphones, the volume is static at full volume and the volume control seems to do nothing at all.
2. When tuning around, connected to a known working antenna, no s-meter changes can be seen.
3. The terminal apps Audio filter sweep, RF filter sweep, and Test ADC I/Q never start.
4. SWR pretty much shows 10s. LPF sweep isn't pegged but I'm not sure to look for exactly either.
?
Mistakes I've made:
- I had trouble soldering the heavier gauge wire enamel wire for the B&C connections on the SWR bridge. In a moment of poor judgement, I think I vaporized the pad on the bottom of the board using too much heat. In desperation, I soldered the wires from the top of the board. Given that I had no trouble doing that, I now think I didn't enough enamel scraped off and the additional heat led to the problem.
- My soldering skills are not stellar yet and I'm only somewhat confident my other joints don't have issues.
?
Any advice on what to look for would be greatly appreciated!
