    Yes this. It’s a pretty easy alignment procedure. I found them online for mine.

    Galaxy SSB receive questions

    Gotta be careful turning those slugs. It’s about impossible to find the right size tuning screwdriver. Plastic ones get destroyed. Ceramic screwdrivers (which is what I use) can crack those cans. I’d open the clarifier on those galaxies if you talk sideband; especially if they’re in a vehicle...

    Anytone At-6666 Pro

    I think Michael w/ Scott’s radios said he was thinking sometime this summer but you know how that goes. He did a quick vid on the sample but didn't show any performance stuff as it’s not a final product.

    New Galaxy DX2547 Radios Produce Buzzing Sound

    I have an update on this. I spoke with Galaxy. This was a limited run, Jan 2024. John wasn’t sure if they normally use MeanWell or the knockoff that’s presently in there. While on the phone, I opened a 3rd one from stock and it has the same problem. I ordered 2 “Genuine” MeanWell power...

    New Galaxy DX2547 Radios Produce Buzzing Sound

    I have purchased a “genuine” MeanWell power supply from Amazon. I will receive on Wednesday. I will install and report back. Also, received showed -12db on the sinad at -112dbm on AM so that’s good.

    New Galaxy DX2547 Radios Produce Buzzing Sound

    Radio: Galaxy dx2547 Serial # Series 2401xxxx Two tested: #24010008 & #24010041 I had a customer complain about a buzzing sound produced by a new Galaxy dx2547. It only does it when using the internal power supply, not when on DC. He returned it and I can confirm he the noise is there...

    Share your useful testing apps, I'll start

    I have used the tone generator in a pinch. Normally I’ll use my Rigol on the bench. The other thing I’ve used is CommTekk’s SINAD. Unfortunately, it’s not a “smartphone” or “tablet” tool or ap. But, it does a good job as a receiver alignment tool. On my main bench, I’ll use my old SINADDER 3...

    Quad 6 or RCI 2970?

    Hands down the quad5N2. Much nicer screen, easy to read, less quirks. Also, it is much more stable on sideband than both of the other radios. The 2970 would be the least stable, followed by the Q6, and then the Q5. The Q6 is not bad but when the temp in your vehicle changes, the Q6 isn’t nearly...

    Home Quansheng UV-K5 Full Band HD Modification

    The one thing that is interesting to me is the Hf ssb. What I’m wondering is if it’s even in frequency. I mean, there’s no clarifier at all.

    RM Italy KL 503 Crunchy

    Never experienced that after doing this mod. Fortunately, you can buy the HD version, now. Presumably the HD version has no driver? That is correct. [edit] Actually, no. That’s incorrect. The driver is still there. I believe they’ve attenuated the input. I don’t understand why they just...

    RM Italy KL 503 Crunchy

    100% there is a lot of input swr with this mod unfortunately, I’ve tried tweaking the coils with no success so far. Never experienced that after doing this mod. Fortunately, you can buy the HD version, now.

    Texas Star DX350 - SSB delay causing loss in power output

    Am signal didn’t look too bad when the AM (attenuation) button was pressed. Only 3w carrier and 9w pep input. Slightly under modulated. I’d recommend 2.5w carrier and 10w pep. Very efficient amp. The original post questioned why the ssb dropped the rf power. As mentioned by several, the ssb...

    Lol yeah. Gosh that dual mosfet thing was like a dozen years ago ‍♂️

    Texas Star DX350 - SSB delay causing loss in power output

    Thanks for that. We will see what happens with various input level and a two-tone signal. I figured there had to be something to that. It doesn’t make any sense, whatsoever, to make the switch a “dual-purpose” switch unless they have good reason.
