SB640 / Split operation

[R. Schmitz]

 Hello dear Heathkit OP's!
Looking for a while for a SB-640 external LMO to make split operation with my
SB-102.Was not successful here in DL. The LMO seems to be very rare. Is
anywhere here on the list a SB-640 for sale ?

May be another possibility for split op. ?
Sometimes the RX SB-301/303 or the TX SB-400/401 are available on
flea-markets. Is it possible to wire the seperate RX or TX with the SB-102
so,that one can use either the SB-102 LMO or the seperate LMO for transceive
work and switch to the both LMO's for split operation. It is difficult for me
to write exactly what I mean, but I think of an operation like Drake
R4C/T4XC. With this line You can work with RX or TX VFO in transceive mode or
with both in split mode. May be, this is possible even with two times SB-102?
Thank You for Your help in advance!
