Thanks for the info. That is an interesting one. What does the LCD report as the SWR value when this occurs? Does the displayed SWR peak higher than it should with modulation, and drop again without modulation, or does it "hang" (maybe indicating self oscillation). Also, can you try a different...

I have used RM Noise with a Hermes Lite 2, with Thetis. It's performance is actually amazing. I have almost zero noise floor at my QTH anyway, but the ability for RM to pull signals from below the noise floor is incredible. The only "annoyance" for me is the round trip processing delay, and the...

Good stuff. The TX bandwidth setting applies to SSB only. See "TONE" in the menu. You can see set result, on a LSB transmission here: https://www.worldwidedx.com/threads/anytone-at-6666-pro.268405/post-844461 73

I have the TF930 and I love mine! I prefer it over a HP that I have. I reference mine to a GPSDO. I added a 10MHz BNC input to the rear panel, for neatness, and I use the front as a 10MHz output if I need another 10MHz source. It has a built-in battery for portable use (I never use it...

They are both very close. But the AT-5555Nii short case will end up slightly shorter than the AT-6666 PRO, as the mic plug and SO-239 will protrude out a bit further on the PRO. (Note: The heatsinks are lined up to a straight edge in these pics, and BNC adaptors are fitted. 73

A summary of the changes between the original and the latest "short case" version: - No more VFO RX muting - CTCSS TONE readout (Hz) and CTCSS scanning. - WX RX, with VHF RX VFO from 136-174MHz FM. - Channel overwrite issues of the old radios, fixed - LCD dimmer control - VOX improvements...

Same factory, and the same radio's with different branding. Sold by different companies that offer different levels of warranty support (some offer none, some offer a lot). Take your pick. 73

It is true - failures can happen to any device. But "bugs" are something different to a failure. (When bugs exist they will be present in most, to all units). What issue did you have?

AT-6666 PRO = QT80 AT-5555Nii (original long case version) = QT60 AT-5555Nii (new short case version) = QT60 PRO 73

For anyone wanting to try the AT-5555Nii short case / QT60 PRO on digital modes, see the attached file for a DIY cable how-to, and the required menu settings. 73

Cheers @c64new . I'm just here to help people out when I can, and to share any info I can. The PRO isn't perfect (what radio is?), but I do think it's the best RTX of its kind we've ever seen, but to each their own. : ) The main thing that will be looked at more in the near future is CW mode...

There is always a way, but it's not currently available publicly. QX understands that some access is needed for the dealer channel, and for the "pro" end users. There is good news: There will be an official solution to this in the near-ish future. Stay tuned. Your example of 20Hz frequency...

That is normal. 15m is a "gift band" - the factory makes no performance claims for 15m. In testing we have found a slight reduction in RX sensitivity, and on TX we see between 40-60w PEP. It's quite useable. The TX output on 15m remains clean with harmonic suppression still achieving around...

Did you just spell DOSY incorrectly? :LOL:

A wise man once said: "with only a power meter, you can only see half of the story". 73

I disagree. PEP is an extremely important measure in RF, and when used correctly, is correct. Anyone with proper calibrated SSB meters can show consistent, repeatable performance to the specifications. (What you see in that video, is totally the opposite of this). Agreed! I saw one of his...

Hi all, I have seen a few people talking about the TONE menu setting (SSB TX Bandwidth / frequency response) in the AT-6666 PRO and QT-80. It allows for either LO 3K or HI 4K settings. I was messing around with one today so I thought some of you might find this interesting. Below are the...

@snippits75 I think you have a CN-901? If so, watch this video:
