Decided to do the Pop fix and it all went well. After looking at how others did the mod to a V3 board I opted to install the components underneath.
I must be missing something though because the side tone is low, inaudible. I changed the resistor R70 to 1k, is there another resistor that needs to be changed. I don¡¯t CW but the keyer has its uses. I trigger my autotuner with it. Works like a charm.
Any way, no more Pop!

WSPR....nice touch!
I¡¯ve made one phone QSO do far and a few WSPR beacons. Getting off to a good start so far.
One thing that¡¯s noticeable is the I hear AM stations on the lower bands.

I decided to start building my V3 uBitx I had since February. I was going to build It in a case but hobby funds are low at the moment so I decided to at least get the basics done in the plastic container it came in. I already replaced the audio chip, I had the WX one and I added a AGC that I purchased from one of our group members. I don¡¯t have a power meter or swr but I¡¯ve put it on a dummy load and tested current, I¡¯m pulling 160ma when it¡¯s on and when I yell it went up to. 600ma. I haven¡¯t played with the 2 bias pots and audio driver. I also upgraded to the latest CEC firmware.
I¡¯m interested in improving the power out and hope a good solution with minimal effort is available soon and I would also like to attack some of the IMD issues and spur issues i¡¯ve been reading about. I eventually want to get the Nextion LCD (sp?) and add a dedicated raspberry pi to it with touchscreen and SDR and sound usb so I can do digital modes. But so far the receiver sounds wonderful it really sounds much better than my commercial Yaesu FT 840 which seems to have a lot of noise coming out compared to the uBitx. Btw I¡¯m not sure if that mic is a good mic for the rig but I can hear myself from another radio and I can confirm that I at least hear my voice.
Anyway I really just wanted to show off these initial pictures with the group I¡¯ll see you guys on the bands.
