Hi,
I am getting a Hammarlund HQ-145 receiver that will most likely need recapping and aligning. I am in Martin County, near Stuart, but not far from Palm Beach County. Thanks, Bob Grimes -- |

You could contact an area radio collector club and request a recommendation
for a repairman in your neck of the woods. http://www.antiqueradio.com/clublist.html Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html |

Thanks, Bob Grimes -- Ain't much to recap in that one. Pete How So? Except for the filter caps, mostly disc ceramic caps IIRC That is correct. When I recapped mine, I just had to replace the three capacitors inside a multi-capacitor can. Two of them were ca. 500 volts in the 40-60 mfd range and were the filter capacitors. In the same can was a 50 volt capacitor, I think 10 or 20 mfd which was part of the audio circuit to the 6AQ5. I just replaced them with discrete components. Everything else I could find were disk ceramics. After I recapped, I couldn't get the thing to work and was somewhat frustrated by this as all the voltages etc checked out and I had done all the tube substitution. What I forgot was that when I took it out of its case I removed a jumper between the prongs of the relay output. You either need a jumper, or and actual send/receive relay contacts or it won't work. Duh. I discovered this when I got the schematic for the version I actually had. There was a small modification in mid production when Hammarlund changed from a tube rectifier (5U4 family) to diodes and I had a schematic of a later version than the one I had. I the schematic (got off of BAMA or some website like that) there was some text which said you had to have the jumper (or relay) or the radio wouldn't work. I don't remember what the relay controled, it might have lifted the center tap of the power transformer. I'll have to look at the schematic again. Recapping was about a 30 minute job, mostly just figuring out where to mount the caps. I added a 4 our 5 tab terminal strip with one of the tabs going to chassis ground. I haven't used the radio at all really. I got it in a rather funny way about 12 years ago. I went to buy a Heath SB-200 amp that a ham was selling on behalf of the estate of a Silent Key. I was trying to negotiate the price downward a bit in the spirit of ham horse trading. So the fellow agreed to my price which was about $50.00 under the asking price. He agreed to the lower price by said "But if I give you that price, you're going to have to take this old receiver off of my hands and he gave it to me. The few times I have had an antenna on it, it seemed to work fine, but my memory of how old tube radios work is a bit dim and these old radios don't have the bells and whistles of the modern ICOM equipment I have in my actual working shack. A crystal filter is no match for modern filters of DSP. Unfortunately I don't have much of a junk box now to throw together a simple CW transmitter, something I did fairly often when I was a kid (I was licensed at age 13, I'm now 66.) Maybe I'll have to get into this as I am leaving another hobby...sailing. My boat was just sunk by two huge oak trees falling on it while at a dock. Jon W3JT Maryland |
