[R-390] New Advance in Modern Technology

[Bob Camp]

Hi

For any kind of fast band switching this has to be a poor solution. I 
suspect they have some way to bypass the preselector in that case. Sort 
of like a Harris RF-551 / RF-590 combo with the ability to bypass the 
551.

I bet they have a ROM and a position sensor on the slug position shaft.

Totally novel and inventive - unless you have seen an R-391 or an ART-13

First tuning is good, then tuning is bad, now tuning is good again.

Gotta go find that bottle of Tequila and get my head straight ...

	Enjoy!
