After a lot of OT entries on the "The making of a Dipole" thread, I decided to start a new one in view of the interest.
Here's a copy of my last entry...
So here's the schematic of the proposed build - time to hit the junk box! After I drew it out I see that the only difference between the SEM and the X-Phase is a ground on the wiper of the "Phase" control. I changed the FET's to something available to me with slightly better specs than the original J310's.
Here's a copy of my last entry...
The "SEM QRM Eliminator", the "WiMo" and the "DK9NL X-Phase" are so similar in the circuit that I suspect that they are direct crib of the SEM - the SEM is about 10 years before the DK9NL - only the connections of the phasing transformer are different - even the component values are the same. I'm in the process of removing all the Tx/Rx switching from the schematics to make just a 'receive only' version - just a handful of components - watch this space!
