[Premium-Rx] Fw: new member and tech help needed!

[Heinz Breuer]

The only difference between versions EK 07, EK 07/D1 and EK 07/D2 is the 
location of the connector backplane and the connectors used. The EK 07 
had the backplane almost in the middle while the EK 07/D1 and EK 07/D2 
has the backplane on the upper left. The EK 07/D2 uses the C connectors 
while the EK 07/D1 uses 13mm RF connectors which are pretty much 
obsolete nowdays.

I have manuals of all versions and there is no info on a digital display 
replacing the mechanical fine dial.
