SB-300/301 regulation mod details

[Mark Graalman WB8JKR]

  I finally sat down and outlined the simple procedure
for providing regulated B+ voltage to the HFO and LMO
in the Heath SB-300/301 receiver.
 This will completely solve the frequency shift problem
from RX to TX when the receiver is used in the
transceive mode with the SB-400/401 transmitter
on the 15 and 10 meter bands.
 Anyone who is interested in the modification details
just send me an E mail and I'll send you the .ZIP file.
