Congratulations to Johan and Dave
I tried a 73/137 sked with Johan this morning (Friday) but was unsuccessful
Have done some 72kHz tests with IK5ZPV. Valerio has sent a .jpg of my
signal received at 2155 on Wed 8th showing 'LDO' then the K
disapearing below the noise (or was it the Alps speckles).
I have an ex-something amplifier with a nice heatsink and a lot of
BD545Ds and BD546Ds. I can't find any data on these devices - can anyone help?
