This indicates that you are attempting to transmit out of band. This is typically a symptom of having the wrong offset (+/-) programmed for that channel. If you visit the Alinco FAQ page you will find this advice for similar models.

Yes you can, page 2-9 of the manual shows: source

Glenn's answer here gave me the nudge I needed. Checking through parameters, I found #11 ... Offset ... 5.000 seemed default setting. With Offset at 5.000 the transmitter was stopped because that would mean operating on an Out of Band frequency. The anonymous OM who posted https://www.youtube.com/watch?v=jPCzJV3gPYQ did an admirable job of walking through ...

The article is mistaken about at least one thing. It may be illegal to market that radio in the US (I honestly don't care to read the tea leaves to find out if that's true or not, but it's certainly possible), but that has no bearing at all on whether you can legally operate one in the US as an amateur. Amateur transcievers don't have to be certified in any ...

There seems to be quite a bit of confusion. First you should tell us if the squelch is for a VHF/UHF set, or some HF equipment. They are very different! A VHF or UHF squelch works by detecting the disappearance (or at least lessening) of noise. That means you can't turn the knob clockwise for increasing sensitivity. The 'most sensitive' point is the point ...

I can't speak to how it compares to the Alinco software, but I've used the RT software for a few different radios and it's straightforward, if pricey. But $50 for the RT solution is probably cheaper than a new mobile/base rig, and if I were in your shoes it's the route I'd take. As for CHIRP compatibility for Yaesu radios, check out the project's ...

I have a different model Alinco radio. I presume that the "cryptic and hostile user interface" you speak of is not the front panel of the radio, but rather part of Alinco's programming software. I didn't want to pay for RT-Systems' expensive software and cable, so I persevered and figured out Alinco's software. What helped a lot was programming a ...

I have not found any of the Alinco models in CHIRP to work with the DR-635T. In an effort to add it none of the methods used by the other models returned any useful data. I tried contacting Alinco for information but was ignored.

Yes, it'll probably work with CHIRP Of course, the first place you'd look would be the CHIRP project page. That doesn't list the DR-635, but it does list the DR-135, DR-235 and DR-435, and that might be a good sign (but clearly not a guarantee, since the hardware might simply be different). In fact, CHIRP's alinco driver has a common DR-x35 base class, ...

I just went through the exact same thing with my own new-to-me DJ-500T (second generation). After a day of poking around, I solved the problem through a hidden menu thanks to some useful posts at the Radio Reference Forums. In my case, I was trying to transmit on UHF (70cm) at 452.5625 MHz, which is a Part 90 channel used for local emergency response. When ...

You may actually want to use speaker out as it will most likely have the proper de-emphasis (6db/octave). Most APRS signals sent our are with pre-emphasis and tapping from your radio at the flat audio signal may actually do more harm than good. Even with a dedicated port for audio out on your radio you probably still have to tune your TNC to the proper ...
