![]() Michael Melland wrote in message ... My Radio Shack DX-440 is a better radio. 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. What's the best source of information on getting the most out of these First, there are a few R-390/R-390A gurus out there. The "Grand Master" Rick Mish (Toledo,OH) http://www.dxing.com/r390/mish.htm Chuck Ripple (Myock, NC) http://www.r390a.com Walter Wilson (Augusta,GA) http://r-390a.us/ Excellent info available here too: http://r-390a.net/ http://www.r-390a.net/Pearls/ The R-390 / R-390A receivers are arguablly one of the finest HF receivers ever built. I have used them both as a hobbiest and professional.... along with Racal, Harris, Watkins-Johnson, Cubic and other receivers. The military went so far as to call several hundred out of mothballs in 1991/92 for use. What other military receiver can you name that has been manufactured from 1951 through 1986 ? BTW.... check out the links on my web page to my R-390A listening post..... "X2" all the way baby ! 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 |
