Re: Adding uv meter .board and leads to ubitx
There are add-on amps but as a stopgap measure, to use the radio until an amp is built and added, just use an amplified computer speaker. I use one and am satisfied to use just one channel. Has to be

Re: CW operation on microBITX
Hi Geoff, Be sure the key contacts are very clean. My key will fail to operate the uBitx in CW mode if there is least imperfection. I installed the CEC software and that improved. It also has other

Re: rotary encoder
It is possible to test the mechanical switch type rotary encoders by using a pair of resistors and LEDs to show the outputs as the knob is turned slowly. Connect a 1500 ohm resistor from +5 to the LED

Re: AGC and FT8
Hi Daimon, I would suggest that you switch it out. With FT8 you will have several signals present within the pass band, some quite strong, others below the noise. Any strong signals that reduce your

Re: Cooling fan Shroud
I choose to run the fan full time. The reason I run the fan while receiving is that it pulls heat out of the small heat sinks. On my original ubitx, I run the finals at 20 volts and use it for
