[Heathkit] DX-60 PTT

[Rev. Don Sanders]

Sorry for the bandwidth but Harry your mailbox rejected my e-mail as being
too full. I attampted to send you the circuit I use for the DX60B PTT.
They were sent to me by BoB  WB2VUF and works well. I plan to add it to the
DX40 also.
Let me know if there is a better address to send the info.

Healthfully yours,
                          DON W4BWS
