Thank you Gary.

Yes, I hope to give 136kHz a good go considering my small garden and QRP
leanings. Last autumn and winter I surprised myself (and others) by
achieving credible results on 500kHz with an ultra-simple QRP station. It
will be tougher on 136kHz certainly, but I start with low expectations that,
with some perseverance, may be exceeded.

Next on the cards is the transverter design and build. There are plenty of
good circuits to grab ideas from, plus I have some of my own. The efficient
small antenna will be the really big challenge.
