So I emailed the owner of the website that had posted that circuit (https://www.redcircuits.com/Page56.htm) asking about IF transformers and this was their reply:
Hello,
thank you for your request.
The transformer used in the prototypes and suggested to the home constructors...
I've been reading up on IF transformers a little.
This had some useful tables and links:
https://www.electronics-tutorials.com/filters/if-amplifier-transformers.htm
I will study it now and post any questions.
Thanks for the extra info.
I want to try this out (to see the maximum distance I can get in real life).
Is this pulse amplitude modulation?
What parameters do I need for the IF transformer? Searching online, I found a few IF transformers and they have things like turns ratio, impedance...
Transformer
Hi guys,
What are the full specifications of that transformer? I've never used an IF transformer before and it seems there are a lot of parameters that need to be specified.
Any help would be useful!
Thanks
