Help: NRD-525 Main tuning
I just received a used NRD-525 from a dealer on ebay. All functions work
except the main tuning knob - it doesn't change the freq at all. The up/down buttons work and the direct entry works. (The lock is not on.) I tried reseating the boards but nothing seems to help. Am I overlooking something simple? The unit supposedly worked 100% okay when shipped, so possibly something came loose in shipping. Greg |
Bad rotary encoder?

It looks like that's the case - I can't find anything loose or ajar. The
seller swears it was working before he shipped it and he is taking it back. I thought maybe something could have gotten knocked loose in shipment, but I don't see anything wrong.

That's a shame. That's a nice rig, otherwise...

Yes, I pressed the Freq button, and the lock was off. The up/down buttons
work, and direct entry works. The rig is pulling in all kinds of stuff tonight on a modest random length wire antenna. But that tuning knob just won't do a thing. I'm gonna send it back to the seller and see if he can figure it out. Aside from that, what a nice radio!

I don't want to be too skeptical, but it sounds a little fishy to me. If
it was well packed and arrived with no obvious damage, I doubt the tuning encoder would have gone bad in shipping, providing that's really the problem. I suppose the seller could have overlooked the tuning knob problem if he's not familiar with this kind of radio. If you can work on it yourself, find out what an encoder costs and ask the seller for a significant reduction in the price to allow for repairing it. Find out what the part(s) cost first. Otherwise I hope you get your money back. Greg wrote: Yes, I pressed the Freq button, and the lock was off. The up/down buttons work, and direct entry works.

Well, I'm suspending my skepticism for now. The seller seems to have a good
rep and I don't have any reason to distrust him. He seems adamant that the radio was working fine when he checked it out. I have returned it to him at his request and I expect he will make good on the deal. I did check with the repair tech at Universal Radio, the only "authorized" repairman in the US for JRC radios, and he said an encoder replacement would run approx $150. I hope the problem is something simpler. I did look under the hood for loose wires & plugs, I reseated the plug-in circuit boards, no joy. I didn't go so far as to disassemble the encoder since I'm not really qualified for that. There may be something in there that got knocked loose or something. Aside from the tuning dial problem, what a great radio! It was pulling in all kinds of stuff. The bands were loaded. Hams and mil coms on SSB were loud and clear and the international broadcasters sounded great, and that was just with the stock filters and built-in speaker. It's such a solid rig, easy to operate, attractive display. I'm hoping for a quick fix! Greg From: starman Organization: Newsfeeds.com http://www.newsfeeds.com 100,000+ UNCENSORED Newsgroups.

I find the Icom R75 (new at $450 or so) seems to have better ergonomics and essentially equal performance... plus on-board DSP, easy computer control, twin pre-amps, etc. I don't miss my NRD-525 at all. The Icom is great bang for the buck :^) -- Anti-Spam address: my last name at his dot com Charles Gillen -- Reston, Virginia, USA |
You say the audio was "not that great" . I have an R-75 and would have to
say the audio is horrible. (using the stock speaker). What do you think of the stock R-75 compared to the 525? "Charles Gillen" wrote in message ...

The 525 also had a tiny speaker like the Icom R75, and in both cases the speaker is shoehorned into the set as an afterthought for "emergency use" only; serious listening requires a better external speaker at least 3 to 4 inches diameter. Even with a good external speaker, the 525 audio still often sounded rather muffled and unclear. In contrast, the Icom with an external speaker sounds sharp and punchy, particularly with SSB. Don't forget both these receivers are for "communications" use, not hi-fi. No use having a good computer if your CRT is crappy... radio is just the same :^) -- Anti-Spam address: my last name at his dot com Charles Gillen -- Reston, Virginia, USA |
I'm with you on the "communications" aspect. I was just curious to hear
your explanation. The 525 would have been my second choice. "Charles Gillen" wrote in message ... "ac-acadaptor" wrote: You say the audio was "not that great" .

Very clear sound on a hifi-amp with good speakers or headphones. It's the bad AF stage "only" on the 525.
