I have returned to 2m WSPR from 10m JT65. 10m JT65 was disappointing again today. I have tuned the FT817 to 144.488980 which should put the rig on 144.489MHz USB when stabilised. This could take some while though!
UPDATE 2038z: 2E0DWP (203km) just spotted. G8LDJ (112km) spotted 7 times so far. Nobody has yet spotted me on 2m WSPR.
UPDATE 2100z: G6AVK (78km) and G8TTI (186km) have now spotted me on 2m WSPR.
UPDATE 2246z: G8OFA (189km) has now spotted me on 2m WSPR. I'll stay on 2m WSPR overnight. Despite 2m WSPR not being recommended, I seem to be managing pretty well with 2W and my big-wheel.
