DK4EI Heinz in Germany was solid S9 this morning on 21.430 at 0900 PDST.
We had a very pleasant QSO and I was also S9.
I had just soldered in the last pin-diode on my Alpha 89 to repair the infamous RX pin-diode issue with this amplifier.
No reason to buy the diodes from Alpha .. the common 1N4007 from Mouser @ $0.15 works nicely and you can
buy 20 for what Alpha will charge you. Mouser also has the Littelfuse fuse for $5 that attempts to protect the
RX diodes, but not quite!
