🧲 Schematic HDR Design Ideas and Experiments

ive completed my new 6 dial hdr unit with witness well so details will be posted latter when i top up my broard band credit which is runing low

Ive seen your You Tube posting and as usual your engineering skills are of a high quality
Can you tell us what the 6 dial HDR will achieve, which your 4 dial HDR`s have not achieved?

it was said more dials gives more tuning ranges so there ya go wise one

Will you eventually end up with 48 dials?, if so i will send you a suitable case to fit them in to, plus a few variable cappys...you can send me a beer for thanks cobber .

48 dials oh no id need a shipping container for my next circuit box then , lol

Yes your right, so why not consider using 48 trimmers?..they are smaller than normal potentiometers and you dont need to place any tuning dials onto their spindles, you only need a suitable screwdriver to directly tune them ..

You can post your next You tube video, showing yourself with several screwdrivers frantically trying to tune the HDR
Believe me, that video would go Viral on the internet! ..

trimpots may not be able to handle the voltage wouldent you think so but maybe i can make a scaled down experimental one pocket version where ill need an electron microscope to see the punny dials then lol

i have seen the British psionics site. .the maximum they did was 6 dials..i may conclude sufficient to make good tuning. .overkill is waste of time n money. .don't u agree..

i tried to upload my hdr project file but its to big and exceeds 10megabytes so leave an email and ill email it to anyone who wants it

Hi, I'm a radio Ham and like drawing schematics, details. I'm looking for projects within my rudimentary skills and budget, but anything unusual is worth studying, whether I can build it or not. I live in Staten Island, KD2NPH, Robert Brown.
