[Milsurplus] [RCA] SRR-13 Article

Fri Aug 5 00:47:46 EDT 2016

HMTry as might, I can find no antique's related definition for "uncommon" but an antique's related definition for "rare" was a snap.  I do find how you have mixed antique and hamfest together interesting although I don't see the connection.  Rare or uncommon should not depend on the location or venue.  I would think the bottom line is either how many items were produced or how many have survived.  Low numbers of either would be rare by my way of thinking and by default, uncommon as well.
I am not all that familiar with the MAB, DAV and have never heard of the Bendix 8D-3 walkie-talkie.  I have little interest in Navy equipment, my main interest is in aircraft radio sets, especially the early frequency synthesized transceivers made by RCA, Collins and some HF green or grey radios of the same era.  Of course there are exceptions, notably Navy 1950's era HF radios made by RCA!
In your opinion, would you define the hallicrafters SX-10, DD-1 dual diversity and the AN/ARC-21 as uncommon or rare?  The first two had production runs in the low hundreds, the ARC-21 was produced in the thousands but few seem to have survived.

Subject: Re: [Milsurplus] [RCA] SRR-13 Article  I think the word is “uncommon”, not “rare”.  The R-808 has only LC selectivity at IF. I think the narrowest is 3 kHz at -6db, something like that. On CW narrow there’s also an audio filter, like with the SRR. I consider this receiver as 2nd place to the SRR because of 1- the 16-32 single swathhigh band, and 2- the IF alignment requiring removal of the IF section. I wonder if people who bought this receiver, knew that when they boughtit.-H  From: Milsurplus [mailto:milsurplus-bounces at mailman.qth.net] On Behalf Of antqradio at sbcglobal.net
