Re: New Question
Mike replacing the regulator on the Radunio will not solve the heat problem. The regulator will source at least 1 amp to run everything that needs 5 Volts. The main problem is that if your supply

Re: New Question
Mike, I run a 2.8" display on a stock v5 with just an added heatsink to the regulator.? You could go the extra step and add a series resistor to drop the 12+ volts (I am running 13.8) to a lower

Nick, If you scroll back through some of the earlier posts on this thread you will see that I have a very similar issue with my v6 that I just assembled in the last two weeks.? It is not as drastic

Hi Evan, QRPGuys' Dummy Load/Power Meter kit arrived. Built and attached. Handy piece of kit for QRP power levels. Anyhow, essentially it confirms the reading I received with the borrowed meter ie 18V

Re: New Question
Yes, my V6 has a heat sink on the Raduino with the 7805. It still gets quite warm to the touch. So you think replacing the one on the Raduino would run both the V6 and the Nextion 5 inch display?

Re: Questions about full kit #ubitxv6
Mike: I think you'll find the board, as shipped, is very reliable. What you're seeing a lot of here are people who want to modify the board in various ways. Jack, W8TEE

Evan, In addition to the L31,L32 filter, note that the emitter resistor in the 45mhz IF at R26 got reduced from 470 to 220 ohms, that would reduce the signal at TP1 when in CW mode. I'd tend to
