Need another Volunteer(s) For Homebrew Reciever

[Jack-KA3ZLR-]

Good Evening All,

 I was wondering if anyone would like to offer up a Homebrew Reciever for the AM Handbook.

All entrys would be very wellcome...

Thanks .

THe one I built is NOT very conducive to someone building a copy.  I used a bank of Racal crapstal filters, a heavy milspec silver (not just plated) tuning cap, etc.  Despite popular misconception, building a receiver isn't that hard.  But a lot depends on the components you have access to.  

Perhaps a receiver using the IF xformers, etc., from a AA5 would be a good project.  3 IF stages would provide decent selectivity and good AVC range.

If I ever get some time I'll work on it.

How about a simple regen?
I have plenty examples and schematics for that.

Hi Tolly    and Bruce if you would like to bring them in and do a small article of reference to help the newer guys along it would be Wonderful, and many thanks...

The thing is we're building this along the lines of new hands coming in and giving it a try.

I had to edit this, Guys i can't begin to say how appreciative I am for all the Input and data coming in, So the way i'd like to say thanks is by the messages that i am recieving whether through PM here or on the phone from interested Amateurs watching this unfold.

So For them and Me Thanks Guys.

I think the regen Idea as some merit.  They are usually simple to build, and have decent performance either in the Glass or sand state versions.
Plus they Historical/nostalgia value of a 'gennie.  

There is a Design by WD4nka ( I think) he called the Regenerodyne. Uses an LO& Mixer to convert to a 2.5mc IF  that feeds a regenerative detector.
not to complicated but has decent performance and multi-band capability.

Something to think about.

A couple thoughts.

   How about a converter? 75/40 Meters to AM broadcastband. Feed the converter to either a home stereo system or a car radio.

   The AM portion of the home stereo may not offer enough selectivity, but for someone starting out it might be an economical way to listen in and develope more interest.
 
    More years ago than I care to remember, I built converters for 10 and 40 meters that fed into a late 50's Oldsmobile car radio on the bench. Lashed together mess but worked quite well.

    Once a converter is built, adding an IF,detector, BFO and audio and a complete receiver is built. A modular approach might be a good route to go.

Just some thoughts

Ramsey sells a kit that does this.

Horst, wa0nuh, has an excellent regen project in the latest ER that just arrived. titled 'A receiver for the Beginner?' Looks great.
