Curt ,
thanks for your input Curt.
Ive already built similar rigs. I was trying to ask others if they have thought about doing this, not how to do it.but good points. Im trying to get others to warm up the soldering iron and build.and maybe think out of the box. I have used several with different transmitters for qsos.
Started repairing an/grc-109s,prc radios,teletype equipment in the US Army Reserves in the Signal corp. Then went to work modifying,repairing and testing and building projects professionally, . sold all my equipment like the spectrum analyzer ,oscope,bridges, signal generators, etc. just have a fluke handheld multimeter, logic probe and pulser,dummy load,variac, dip meter , frequnecy counters(calibrated),variable pwr supply(Still using my old Lambda power supply), swr meter,soldering iron and lots solder wick HI HI for all the mistakes i make.ONe of my signal meters was a boonten if i recall,might be wrong though. been decades since i used it.It was old school equipment. Not like todays equipment.
besides the kits, im striving for a complete homebrewed station.. building some for my Son .it will be there for him even after im gone.
Also putting together a complete 4sqrp station . awhile back recently purchased the cricket 80 but havent assembled it yet due to lack of solder at the time.HI HI. will be purchasing most of their kits and accessories for a complete station with various options. Sold my icom 746. even though i loved the 6 meters on it, ive built a transistor based 6 meter transceiver that runs on 9vdc to 12vdc. depending on the source voltage is what you will get out in power., Its capable of CW and SSB. used the sb1 mixer, varactor diodes for tuning,some of the tuning cans came from some CBs, uses a d-104 astatic microphone wired up to it.Qrp CW,SSB .
Been QRP since licensed, and followed Doug Demaw, and George Dobbs religiously when they were active. Have alot of their works in my Library to show respect for their contributions to the Hobby and also to have some of the best QRP info on the planet.
regens are basic info for beginners. testing them and repairing them are at the same level. Simple.
I even love using ceramic resonators. even though limited on bands,on the market, 40 meters is plenty. They are very stable. You might try them in your regens. It makes them more pleasant to listen to.Also a fellow ham designed a regen with ceramic filter and with audio filters . I came across this little design on the web,and due to rules here,i wont list the ham or the name of this regen, but I believe that this simple design ,you can add a digital vfo to this rig. just have to change some of the components to match impedances and coupling .Its a single signal regen.pretty creative this ham was.This regen would make a great companion for any 4sqrp rig.
YES adding a digital vfo is possible in my own opinion by substituting the ceramic resonator with the vfo and only if you build the unit "out of the box" so to speak. And with using a ceramic resonator one can eliminate the LC portion of the regenerative receiver..At least several hams have successfully built ceramic resonator regens without the LC circuit.Im one of them
