Hallicrafters 5-10 receiver - UK Vintage Radio Repair and Restoration Discussion Forum

Keith · 12th Oct 2022, 7:09 pm

I recently acquired this receiver, made by Hallicrafters to cover the US 10m and 5m bands of the day. Unfortunately, a previous owner has modified the lower frequency band front end, presumably to cover 15m, as the coverage has been dropped by about 10MHz. It looks like the RF, mixer and LO coils have been modified so I'm hoping someone out there has the original coil winding information. Any information appreciated.

Station X,
Thanks for the links. Looks like those pages are all the info available. I shall have to resort to trial and error!

You will find some information on the https://elektrotanya.com site they have circuits for the S-21 5-10 and a parts list.

There is not much information but some.

When you get the search results there are 3 references that I have found up to now so keep going through the lists.

Hi,

Are these any help?

Kind regards

Thanks for the further replies. All the same info I'm afraid. However, it shouldn't be too difficult to get the tuned circuits back where they were, at least for the 10m AM band. Tracking might be a different story though!
