I do believe that crystal filters are available and it can be modded to be "competition" grade. Perhaps Drake's most famous. Though I do think in recent years the performance has been eclipsed by the likes of elecraft and other high end radios with more features also. But if you were to have a "legends" list this would belong on it imo.
@@bramfam4 I'll post this as general information. The Drake R4 series of receivers were designed to be used with the T4X series of transmitters. There are about a half dozen RCA cables, like VCR patch cables, that are used to connect the two units together and enable the various functions. The R4 can be used as a standalone receiver because they have their own power supply built in. To do this you have to provide a speaker, and insert a shorting plug in the "mute" and "PTO LAMP" sockets on the rear apron. Range crystals are still available thanks to AF4K. I recently had the opportunity to use a R-4C and found it to be as competent as anything else out there. Unless a golden screwdriver has been inside spraying the controls with CRC QD plastic safe cleaner will probably be all that the receiver needs to return it to service.

Tune in on Radio Moscow, Radio Habana, and Radio Berlin International.
It's an early ham receiver not a general coverage filter.
@@metatechnologistThere were range crystals available for the R-4C that enabled it to be used for SWL.
There's a jumper plug that you have to insert to get the dial light to work when you're using it standalone.
Gosh thank you! I was wondering about that.
