What range did you use on your meter? The ones in the transmit chain are working so when in transmit, you should have 0.6V there. Howard

Re: RF power chain mods and improvements..
Arv, You're right, it works at 15,12,10m. And while I don't have a spectrum analyzer to verify this,? my impression is that with mike gain sufficiently down the signal is legal. Unfortunately, if

Re: Correct levels from computer to uBitx in digimodes
A VERY IMPORTANT point! I'm fortunate to have an Icom7300 with a visible spectrum ?display. I ordered a handy smeter kit and am going to put it on the ubitx Mike input line to set the level

To check if the trifilars are shorted I have to unsolder them, so I wait a little with that. But I measured the 3904:s. All of them had zero volts between base and emitter. I also measured the voltage

Re: RF power chain mods and improvements..
The uBITX does actually work on 15M, 12M, and 10M (and yes it does work on 11M as evidenced by the number of CB'ers who have purchased it). Power output is much lower on the higher bands, but is still

Re: RF power chain mods and improvements..
With the 86mhz filter you need 98mhz and 74mhz for downconversion to 12mhz. Thn you need LO to signal, with 86mhz filter maybe (have to run a spur table) 83 down to 55mhz? (LO below IF) will work.?

Correct levels from computer to uBitx in digimodes
How does one determine the correct output level from computer to mic in on the uBitx for digimodes like FT8 JT65 PSK etc.? On my FT817 / 897 I watch ALC level. How to do this on the uBitx ? Jan PD0JBZ

That is good news, I would look at one of the trifilar interstage transformer being shorted. I mentioned the numbers earlier. If the transformers are fine then a dry solder in the RX chain or filter
