Yeah, I ordered a couple of 455 KHz crystals today. It would be good to have another on hand. FYI, I stumble onto these things because I restore boat anchors (mostly receivers) for educational and

I've owned several SX-110's over the years, including the one I used as a Novice back in '67, that was like new I acquired from original owner. Never had any issues with xtal instability. They all

I am not an expert but think this is not normal.? ?It looks like the crystal holder comes apart.? ?Perhaps cleaning crystal and electrodes will fix it.Sent from my Galaxy

Attached is a photo of the crystal in my SX-110. I pulled the crystal to test its resonant frequency using a sig gen and scope, and the darn thing is so unstable it’s driving me loopy. The resonant

Hi Randy Yes it was the converter. I removed the transformer, and the top end cap and broken slug pieces. The slug was broken where the lighter colored material meets the darker material , I carefully

I have a truly collector condition SX-71 and matching speaker for sale in central MD. It is the version w/o 15m calibration (use the logging scale). Downsizing the collection, here, for better or

Good luck with yours. Edit: What is interesting, using the FT8 audio scale, you can measure your receiver drift in cycles and its direction, up or down. Who knew, FT8 could be used as a quasi

Good to hear that, Bill. I hope to be able to do that with my 1937 SX16 whenever I manage to get it restored! Peter, G4ADJ

Thanks Scott. The subchassis sounds like it's the 2.0xx MHz converter. Did you try to repair the loose slug? If so, how did you do it? Randy Get Outlook for Android<https://aka.ms/ghei36>

I had a broken slug on my Sx-71, I discovered it because it would tune when upside down, and rite side up it wouldn't. it was on the subchassis in the left rear. ________________________________ Sent:

Been using my SX-17 to cruise around the SW bands, haven't done that in some time but out of curiosity, I wanted to see if it? was possible to decode FT8 using acoustical coupling, from the SX-17

Forgot to mention – it will be interesting to see if the 453.48 MHz frequency I allegedly “located” on that dip is, in fact, the actual frequency of the crystal – and if the 1st IF is already

Randy, I’ve been working on a SX-110, which uses the same type of instruction, and it’s confusing and seems counter-intuitive for peaking the first IF transformer. Once you’ve identified the

New to the forum and restoring an SX-71. I'm trying to go through the alignment procedure in the manual. I'm stuck at Step 2 adjusting the IF coil associated with the 455 kHz crystal (adjusting tank

The links were to worldradiohistory.orgThis site has a perfectly enormous collection of stuff on it .? I suggest exploring.? QST is on the ARRL site but I believe one must be a member to access the

Hi Richard and friends too I don’t know where they reside other than somewhere in the clouds. I just put “qst 1946” into google and that’s what I got …Oct came first and amazing there was

The last one has 8 pages on the receiver and I didn't count but at least 30 cooperative dealer ads featuring it.? Hallicrafters was really pushing it.??BTW a really thick edition? A reaction to

Steve; and dedicated followers; I see no indication of variations or changes to the 42 in MY second edition Ostermans or in MY Dachis 1996 printing. They managed to find the later revision info to

Per the Osterman book, the SX-42 was on the market from 1947 – 1950. However, information on another site shows that it was advertised as far back as the December ’46 issue of Radio News (see
