Thank you all that took time to weigh in on this topic.? I have a few dds vfo's already (probably 5 including my Qrp-Labs arduino shield)? ?What I was trying to see was there a modern implementation of the h&p to use on some of the older style of vfo's.? I want to build a stable vfo without resorting to either arduino or computer control.? ?Having said that I am going to use the arduino shield as an external vfo for my Heathkit DX-60b currently under restoration.? ?I would love to use the Heathkit HG-10b external vfo but it wanders all over the band.
Anyway.? Thanks
Mike? Ve7epq?
