Hi Meir,
Thanks for the update..Do you have any reference material to support your assertion that the R648 was not, in part, designed as a replacement for the BC 348? Honestly, I don't know and the my reason for the post.
I have found 2 sites that state/suggest the R648 was infact a replacement for the BC348 including the bottom of the page for this link BELOW.
http://www.mrca.ar88.net/photo_gallery/2002_meet_pix/meet_pix.html
Another link with tech info but no historical info on the R648.
http://staff.salisbury.edu/~rafantini/ARR41modifications.htm
There seems to be a lot of info on the R389, 390, 390A, 391 and 392 but very little on the R648. I am willing to pay for copies of any historical info that you may have. Do you have any idea how many R648's were built? I watch epay for this and other receivers bit have only seen 5 or 6 listings over the last 15 years.
Given the general performance of the R648, I am very surprised there is not more info posted on the web.
I know you have a lot of Military communications related knowledge as well as equipment and documentation. I have a very nice tech manual on the R648 but it has no historical content. Any info you can provide will be GREATLY appreciated.
I hope some of the readers of this list have some specific info regarding the R648.

Hi Group,
I have followed this list for a number of years and have heard little mention of the R-648 receiver. There is a R-648 list but I hear almost no discussion there either.
Not sure how many 648's were built but I own one and have repaired several others for clients. It's actually a pretty decent receiver also built by Collins as an COLLINS ARR-41/R-648 RECEIVER. I see them on epay from time to time and they generally sell for somewhere between $350 for fair examples, operation UNKNOWN to well over $900 for good examples promised to WORK!
It covers 190 ? 550 Kc and 2 ? 25 Mc skipping the AM broadcast band and was designed for aircraft utility with an aluminum frame to reduce weight. It uses a similar counter display used on the 390, 390A's Veeder counter, and others but a little different.
Scroll down this page for a pic.
http://www.mrca.ar88.net/photo_gallery/2002_meet_pix/meet_pix.html
I believe all of these were built with dynamotor supplies but many were converted to DC operation once Hams started to get them from the surplus market.
My understanding is the R648 was to replace the aging BC 348's but still being a tube unit when Solid State receivers were becoming more readily available. the R648 was a day late and probably MANY dollars short.
I am sure this is a NON-OFF TOPIC receiver question/discussion but was wondering if there are others who also use this receiver? As the TV commercial from the 80's, I think, said, "TRY IT YOU MIGHT LIKE IT."
Anyone have an idea on how many were built? Any additional historical info will be GREATLY appreciated. I had asked the group about 2 years ago if there was interest in manuals since I have an EXCELLENT copy with legible schematics and supplemental notes but only heard back form 4 or 5 people; not enough to justify the cost of having a batch printed.
Again, any HISTORICAL info will be GREATLY appreciated.

Thanks Dave and Jeff. I will start working on it soon. Looks like I need
an audio connector and maybe power connector. Another project is ahead.

Still lurking. Recently moved to a new house where outside antennas are allowed and am looking forward to using my radios again. Among others, I have a mostly Collins R-390, an R-392 and a 51J-4 that needs to be put back together. Bought a CV-591A at Hamcom a couple years ago and am looking forward to pairing it with the R-390.
I recently bought an Afedri SDR and am planning to sell my Drake R8B and TenTec RX350D.

Glenn,
The ARR-41/R-648 was NOT the replacement for the BC-348. It was contracted and purposed as the auxiliary tuneable receiver to accompany the digitally step tuned transceivers which replaced the AN/ARC-8 systems (ART-13 transmitter/BC-348 receiver), such as the ARC-65 and ARC-94 on military aircraft.
