The things are difficult to tune, require annual tweaks, use parts no longer made, burn copious amounts of electricity and will ruin any piece of furniture you put them on top of. Amen to all of that. I used to have both (390 and 390A). They are a perfect example of Rube Goldberg-ish design, the reception is nothing spectacular and the audio quality is mediocre at best. I bought them just so I could say I had owned them, and sold them both after about 6 months. This was about 15 years ago. Every "radio owner/collector" should own one or the other at some point, just to see one in action. They are marvels of mechanical complexity, but no match for even a $150 portable. My Radio Shack DX-440 is a better radio. Jim I used to repair R-392's when I was in the Army. If one is set up properly, its performance is astounding. However, I've never seen one in civilian life that was properly maintained (other than my own and the ones I set up for friends). The 392 and its sister R-390's are high maintainence items and almost no one takes the time or has the knowledge and technique to make them sing.

Whaaa ?.... while an R-390A isn't for the "electronically challenged" it is far from a maintenance problem once properly aligned. A healthy, properly aligned R-390A should have sensitivity at 4 KHz of under .5 microvolts in AM.... and they are remarkably stable. My R-390A is still in perfect tune and it's been up and running 24/7 (except during storms) for 2 years now. The R-390 series is NOT a difficult radio to work on... especially compared to some solid state radios of late with their surface mount components.

Mike -- Michael Melland, W9WIS Winneconne, WI USA http://webpages.charter.net/w9wis SO... now I have to ask... again... Was it five years back that there was a big flap at the Pentagon? Some hams raised a big noise about all those 390's, 390a's and assorted Collins gear that was being destroyed---even had photographs on the web of hundreds of those rigs strapped together on pallets in the salvage yards waiting to be crushed. Some fellow, Top Brass, was also a ham and said that gear was going to turned over to the ham community instead of being destroyed. What happened to all that stuff? I have yet to see it on the shelves of surplus dealers. Maybe it made it's way to Russia or China perhaps. RG |

That was the St Julian's Creek Massacre.
Many of the radios ended up at Fair Radio. They were distinguishable by a broad blue paint stripe down the front.... and lots of sand and debris inside from being stored outside in a heap for over a year. Mike, W9WIS |

They can be shipped by truck. Nothing else like having a semi-truck pull up in front of the house and knowing your new receiver has arrived ! jw wb9uai It's also possible to ship it by bus, like Trailways. This is one of the safest ways to ship heavy/fragile equipment. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
Thanks, Frank, for the link. Sad.
The R390A/URR Ultimate Performance, General Coverage AM & CW Receiver It works fine for SSB, too. In 1960, during a sea trial on the USS Little Rock as a Philco Tech Rep, I used one to run phone patches. The rig was a 1500 watt TMC vfo phasing rig. (It had an 8 Hz frequency variation due to the vibration on the variable capacitor caused by a bent propeller shaft. LOL) I had such great luck with the stock R390A (in the main transmitter room) and the Navy guys in Radio Central were having so much trouble with the TMC ssb adapters they had down there, they started using the 390's without the adapters as I suggested.

Not as something which will be useful and valueable to someone else, but as scrap. Anyway, the picture was taken years ago, and it seems Fair Radio ended up with many of these radios. I was seriously considering getting a R-390 a few years ago. I have some test equipment, and the servicing documentation is excellent. I figured I could get it going very nicely. I didn't. Hobby money's a little tight now, and I really don't have the space. Oh, well. Other radios are more practical, but few are so cool. Frank Dresser |
