I have a spare bitx40. I also have other 40m qrp portable radios cw and ssb. Id like to get on 2m ssb/cw. I do not have a 10m rig. The choice is to either mod the transverter to use a 7mhz transceiver

#bitx40 #6meters

The problem is that the Bitx40 (as referenced in the subject of this thread) only does 40m, so a transverter with a 28MHz IF would not work.

Why? Whats the problem with 28MHz?

#bitx40 #6meters

Use the Unranian xvrrts at 28 MHz

#bitx40 #6meters

Would 7mhz be too low as an IF for a transverter for 2m? What about 6m? Im thinking 130mhz (LO - IF) might be too close to desired RF of 144. 14MHZ separation at 144mhz only 10% difference. Obviously

Peter, First ditch the 3904s or the similar parts used are near dead at 6M and forget 2M as the layout is unfriendly to VHF there. You will need a bandpass filter at 50Mhz. A dds generally doesn't rea

We've had some discussion about moving the uBitx up into VHF. Conclusion seemed to be that the best bet would be to run it at 30mhz and use one of the Ukranian transverters. The FM thing came up then,

#bitx40 #6meters

Not a trivial hack. I'd suspect you are replacing the first mixer, the bidi RF amp in front of that, the 7mhz BPF, the entire transmit amplifier chain including silicon and transformers, and the outpu

Many would have the old Bitx40 (especially the free running VFO version) and have little use for it now they have a uBitx. A possible idea could be to convert it to 6 metres and potentially 2 metres a
