[Hammarlund] Ultimate receiver??

Fri Jul 5 10:46:22 EDT 2013

 I knew of one intercept station that was aware of the preference for SP-600's for RFP (Radio Finger Printing).
The local maintenance shop at the site ginned up an outboard freq. counter to solve that problem. (Of course
an R-390 was no better than the local calibration shop, something we on the IG team looked.)  One of the service
officers on the IG team wanted to "gig" (write up) this as a violation of policy. I convinced him that the thing
that was dumb was the policy, not the hook-up.

We had a VERY few Racals, used in a special project. The problem with Racals was that they weren't US. I rather
liked them the few times I got to use one, but like many things in the military, we needed a supply pipeline. Racal
ultimately got a US presence (did they work with Watkins-Johnson?) WJ built a lot of our VHF/UHF gear and
had a facility in suburban Washington to deal with the "Bigger" DOD. (I was concerned only with intercept-type
activities.)

Again, I was more of a policy and budget guy, so my exposures to these Rcvrs was transitory. Unlike most policy
and budget guys, I at least knew how receivers (and other gear) worked and I knew which end of a soldering iron
was the hot side.

I guess I could chime in here as well. I own many of these fine receivers(only ones with tubes, Chuck didn't specify tube or SS) This doesn't appear to be a thread about "favorites" but the quest for the "ultimate" receiver. As previously stated, It Depends...
I had a visitor about a year ago who worked in Government Ops who used R-390/390A's and SP-600's to "fingerprint" CW transmitters.
He said that he and many of his compatriots preferred the SP-600's to the R-390 radios but were prohibited to use the 600's for the high speed scope photography because you couldn't verify the exact frequency. He preferres the audio from the 600's and of course the ease of tuning. One receiver that has been left out (unless I missed it) is the British Racal RA-17 family of receivers. I have 3 of them (2-"L" models and a MKII/C3) and it seems to me that bandcruising reached a new speed with these radios. The only problem as I see it is the preselector "chasing" that you have to do to keep the front end peaked. It would be nice to have several tuned RF stages in the front end instead of the cascode single stage. But the tuning is fast and the radio performs very well. Besides, they appear in numerous James Bond movies, that has to count for something!!! 73 Ross W1EKG

Regarding the Rohde @ Schwarz EK07 I have about 8-10 in various 
condition which I bought for my friend Hank Arney KN6DI in Texas. He 
used to repair and restore these and resold them to the ham community. 
Unfortunately Hank broke his hips repeatedly and now lives in a medical 
care unit. He can no longer work on these receivers.
I had an arrangement with Hank he got these at what I paid to get them 
no profit no handling - rien nada niente. In return he stored and packed 
my toys I bought on various lists and eBay USA.
If anybody is interested I am eager to sell these receivers. I have them 
in storage for years already hoping that Hank's condition would improve. 
I would prefer to sell these receivers in a bundle deal. I do have 
pallet size metal shipping boxes ex German army. Shipment via seafreight 
is quite cheap. I currently have a last shipment inbound which Hank's 
sister arranged. About 8 cubic meters (approx. 300 cubic feed), probably 
2-3 tons. As a hint seafreight for this is about $1000. Local transport 
to and from port is each more than the seafreight itself.
I can also throw in a few Siemens E311 and Russian 250M if anybody wants 
to have these as well. Probably some other German boatanchors 
(Telefunken and Siemens 'Rainbow', Lorenz etc.) as well. Let alone a 
couple premium receivers Telefunken E1500, E1800/3 and E1800A, also 
Rhode @ Schwarz EK47, EK56/4 but this is the wrong forum for that sand 
state stuff.
I am not a dealer but a collector with just too many toys and will sell 
these at my cost. If somebody lives not too far from a major seaport and 
could pick up the shipment I would drive the boxes to Bremerhaven myself 
to avoid the expensive local transportation.
