Another problem that can be VERY critical to get right is the 'locking point" for the "Wadley-Loop" oscillator within a particular band range. If it "locks" with the frequency range slightly "off center (above or below the clear part of the window, but still readable) accept the slight alignment error! The trimmers that control each band of that circuit are VERY difficult to "get right" and can become extremely touchy to adjust. The RCA transistors are probably, by now, almost "unobtainium".

It came in the orginal wooden crate, a true time capsule. It is working on all bands but unfortunately it is far off, in the lowest band it locks when there is nothing in the display. It gets better as frequency goes up because the markings are closer together. I haven't touched it so far in fear to make things worse. I even found a LF converter and a speaker for it, but it took me a couple years on eBay and way too much money. The cabinets for the speaker and the LF converter need a touch up or even a complete repaint, any hint on a available color? vy 73 de Heinz DH2FA, KM5VT Sandy schrieb: > Jim, > I've worked on many of those YEARS ago but never heard that problem! > Make a recording file at different degrees of selectivity and send it to > me. > > One thing you must be VERY careful of!

Also, the built-in speaker is very tiny and unpleasant to listen to except for occasional monitoring. Still, it works well, and the interface switching is very convenient. Heinz, it's been a decade since I aligned the synthesizer, but as I recall it wasn't difficult to center the lock points in the display window. I"d have to check the manual agian, but I think your locking misalignment on the lowest band may require just a single trimmer cap adjustment. I also aligned Howard Mill's radio, then, and it went into alignment smoothly also. Sandy, I agree completely with your comments about the frail end points on the tuning dial. I'm always careful near the end of the turning range. Because there's no dial scale, other than the micrometer PW dial, it's sometimes hard to know if one is at the low or high end of the tuning range. I'm still pulling my hair out over the CW/SSB sound of the radio. (I don't have the ability to send an audio file, unfortunately).SSB stations sound like they're speaking with mush in their mouth, and CW stations have a woosh sound. I hear it on all filter selections, which rules out the pot core resonators (which are switched out on the 8 and 5 kHz positions). I'll continue to play with it today. Wish I had another radio I could compare the sound to. To me, the most frustrating part of the alignment is setting the VFO end points. I spent a couple of hours last night, but couldn't get them any closer than about 2.5 kHz to the 500kHz span. Adjusting the coil is easy, but changing the touchy trimmer cap causes the VFO to drift for about 5 kHz for about ten minutes, so one just has to ballpark the adjusment and wait for things to settle down. Despite the complaints, the HRO-500 is a great radio. It's a crossover design, just as solid state electronics was taking hold, and it has a foot in both eras. And, of course, the styling is fabulous. I wish I knew more about the history of the radio, and also its rare HRO-600 successor. The HRO-600 has much better performance, as one would expect, but lacks the classy styling of the HRO-500. 73, Jim Garland W8ZR > -----Original Message----- > From: owner-boatanchors@theporch.com [mailto:owner-boatanchors@theporch.com] On > Behalf Of Heinz Breuer > Sent: Saturday, December 12, 2009 4:53 AM > To: Old Tube Radios > Cc: Old Tube Radios > Subject: Re: HRO-500 question > > Hello, > > I have one of these California military treasures too.

These were all sets that had been in service for years. Transistors were unavailable at the time and there is no really "good" substitue for them. At least I didn't find any. Setting the calibration to agree exactly with the PW dial is always a daunting task. Can take several hours of tweaking and waiting! I have never seen the HRO-600. There was an FCC inspector here in New Orleans who had a new HRO-500 he bought when they were out for around a year. He loved it and carried it around on his car seat for a long time. Art Hallum (don't remember his callsign). He was transferred to another office and I lost track of him years ago. Could be even an "SK" today. 73, Sandy W5TVW ----- Original Message ----- From: "Jim Garland" <4cx250b@muohio.edu> To: "Old Tube Radios" Sent: Saturday, December 12, 2009 8:36 AM Subject: RE: HRO-500 question > Hi Heinz and Sandy, > I also managed to pay too much on eBay for an LF-10, which I've not used > except to listen to WWVH at 100 kHz and a few airport beacon stations. > Also, > the built-in speaker is very tiny and unpleasant to listen to except for > occasional monitoring.

I pulled it and found a definate dip at 10 Mcs on a grid dip meter so looked further, on bands 17 and 18 there was no output from the xtal oscillator, suspicion fell on the large rotary switch. The switch contacts checked out with a VOM, but during the checking it was discovered that both sides of C153/C154 were grounded, switching bands had no effect. By poking around in the all-but-inaccessible xtal oscillator compartment I discovered the bare wire going from C153/C154 to the rotary switch rear wafer was touching the bare wire on the grounded side of the other row of trimmers. After minor bending and an alignment the radio is working very well. There's a very minor oscillation when receiving strong stations, sort of like a very weak BFO slightly off to one side, but that will wait for another day.
