I,Q, and HRO: VK2BLQ's Phasing Receiver with an HRO Dial

I had occasionally fantasized about connecting Armand's HRO dial to the rotary encoder of an Si5351, but I think this was more of a nightmare than a fantasy.   I don't think Stephen VK2BLQ went this far -- I suspect that his HRO dial was connected to an analog VFO.  But still, the combination of HRO with I&Q seems a bit edgy...  FB Stephen.  Please send us more info on this amazing receiver. 

  

Hi Bill,

Hope you are safe there with the bad weather.

Recently you  mentioned HRO dials and the need to build a radio around one and Pete has been discussing phasing SSB; attached photo is a phasing receiver on 80 and 40 m, a combination of both HRO and IQ that I built many years ago, and thanks to Pete I shall get it running again.

And Bill, like you I am from the IGY of 1958 and retired with more free time on my hands.

Best regards to you and your family, especially young Billy.

Stephen,

VK2BLQ
