Having spent the last six weeks or so building low current radios I am beginning to realise that a PP3 battery is far too large for this type of SOTA operating. I suspect that 400 QSOs are quite possible and I don’t really want to spend all summer running one battery down. I will probably just continue to use the first battery and see how that does.
Thus I think that I will finish off the new low-current RX and package it up as a curiosity - and a useful exercise in self training!
My attention is starting to switch to VHF. While I have built lots of VHF things I have never built a VHF transceiver. I quite fancy building a 2m CW transceiver and this is made much simpler with this device:
With a bit of care a 15W CW rig will be quite simple to make - so that’s the target for the summer. I also have a desire to build a 23cm transceiver - but that can wait.
