Using the Raduino with other QRP radios
I was wondering if anyone has tried using the Raduino as a VFO to replace the crystal on some other QRP radios to replace the crystal like the Rockmite II, the 49er and other small minimal power QRP r

UBitx v5 (CEC v 1.2) Tunig Clicks
not sure where the audible cliek comes from, but changing the encoder to one without clicks removes it.. plus you can move around the band much faster..

V5 uBitx CW issues
I took the antenna off and tested the uBitx straight into a 50 ohm dummy load and it performed flawlessly on the upper bands as well. I don't have ferrite beads I can use at the moment but will get so

uBitx V3 transmit probles.
I have a V3 that just quit transmitting. It appeared the finals just went out. I replaced the finals (used sockets per advice from another user) and still no output. It is a good thing that I put them

Purchase just the uBitx v5 motherboard?
it would be a nice option to be able to purchase just the uBitx v5 main board only. There are several who have a v3 radio that would like to upgrade but already have all the hardware, wiring, pots and

ubitx or bitx 40
I have both. Two different radios. They have a lot ifsimilarities, a lot of differences. If you are only going to get one, get the uBitx as it is the entire HF band, not just 40 meters.
