I'm hoping someone may have experience with this issue so I'll put it out here for review. I recently received and built the Cricket 40 kit. When I first built the kit, it was discovered (only after testing) that I was missing the SS8550 for Q7 and instead had a 2N7000 in that location. The result of this was that when turned on it sounded as if the keyer was constantly pressed. After receiving a replacement I changed Q7 to the SS8550 and now it will key correctly. Now my issue is that I have no receive audio whatsoever. After digging through some forums I found one instance where it was mentioned to check for flux contamination so just to be sure I did make sure I cleaned the board thoroughly, although my soldering was kept as neat and clean as possible. I found also a note about checking the center leg of Q4 to see if voltage here was above 6 volts. In my case it was around 4. The recommendation was to place a 1 M ohm resistor across D1. I have done this and now the voltage on Q4 center leg is about 8.5 volts but I still have no receive audio. when I press the keyer, I do hear the sidetone and having a receiver nearby I do seem to receive. It seems something is causing the receive side to be muted but I'm stumped at this point. Has anyone experienced similar or does someone perhaps have a suggestion to check further?
I'm new to the 4 State QRP Forums so I apologize if I entered this in the wrong place. I'm currently holding a technician license, working to learn code as well as studying for the general test. I wanted to build a small kit and play around with it a bit but it's turned into a troubleshooting project more than using a transceiver. All part of the fun.
Thanks for any help you might be able to provide.
