Will version 1.5 have a completed multimode squelch
I'm really hoping version 1.5 has a proper squelch function. Every rig I have has a squelch that works on all modes. The existing FM squelch really needs some work too. It is constantly breaking squelch and filling the room with a loud burst of static, then goes silent again. I don't think a properly operating multi-mode squelch function is too much to ask for.

Tim says 1.5 will NOT have Squelch ....... I simply cant believe ANY radio, especially one that will receive multiple signals don't have friggin squelch !
Squelch is to EASY to write .... all you do is mute according to meter reading.
Im starting to think the flex has tubes ...... back to the stone age.
Ive talked 2 people outta buying flex till they get squelch, I had to show one guy on mine because he didn't believe me, he said that's crazy, I agree!
My wording wasn't so good ..... neither considered no squelch acceptable, both assumed it would have squelch like any other radio does, both like me tried to run demo software before buying but couldn't find it.
Digital just mute sure.
I find plenty people that feel like me, I cant imagine listening to multiple hf all day with no squelch.
Many, like me have more then one freq they like to monitor and listen for friends.
What demo software?
Did I miss this?

You along with some others forget this radio is in development, so as this goes we wait for things to improve step by step, most understand this.

You may already be aware of this but I want to make sure the Flex Community knew. I appreciate and learn something new from the Flex Community every week.

When I travel in my RV after the close of the RV Service net on 7191 at 09:00 EST I will leave my TS-480 on frequency and set the squelch so if some of my fellow travelers pop in I'll hear them without listening to all the noise. I'm looking forward to taking the FLEX 6500 mobile this fall for several trips.
Tim, I hope this helps you to understand those of use the Flex 6000 in other ways have for Squelch. And don't get me wrong The 6500 is the best RX I have ever owned or used both commercial and amateur.
Many rigs have a squelch for HF but few work very well. On most rigs setting squelch to a usable level is difficult due to QSB constantly varying received signal strengths.
I've heard of a workable approach to HF squelch for SSB that detects speech or another that compares the energy in the upper & lower sideband channels but it's not clear to me of their effectiveness with other modes.
57 years as a ham & I can't remember anyone ever using HF squelch due to these reasons.
Flex could add marginal squelch that doesn’t work any better than other rigs but duplicating mediocrity hasn’t been their style. It seems to me that taking on this difficult task would be a huge diversion of resources that should go elsewhere.
As a Flex 6300 owner I encourage Flex to proceed on the current plan until they have time to do it better than anyone else.
I would like to use it for monitoring openings on both 2m SSB and 6m SSB. I also have a few marine frequencies, and a few frequencies on 160, 40 and 20m that I listen to on a continual basis. It would be very nice to have a squelch that I could turn up the volume but not have to listen to the background hiss / white noise all day long. The AGC-T isn't a substitute for squelch.
I have 8 slice receivers and I'd like to be able to use them more comfortably. How difficult is squelch on SSB? Shoot every rig on the market has it.

1) When the second (or third or fourth) slice is squelched, the audio levels act just as if they were muted, meaning that the audio power is NOT balanced between the various slices. When squelch is broken, the audio power sharing is implemented.
2) It would be especially nice if the SSB Squelch was based upon audio detection of the voice rather than merely based upon signal strength. This would prevent random noise bursts, sweeps, carriers, etc. from opening the squelch. This would be much more effective.
3) It would be really nice to have some type of encoded squelch similar to DCS or the tone burst used on aviation HF that could be used to open the squelch on a channel - i.e. for EOC uses, emergency nets, etc. it could be as simple as sending a string of dits, an encoded sequences of pulses, or a two or three tone burst similar to the automatic mode identification on some of the digital modes.
My main thought in any of these options, and in using an HF squelch in general, is to limit unnecessary noise in my receiver speakers or headphones, especially when monitoring fairly inactive bands while working other bands at the same time. Even when sliding one or two slices to the right or left and adjusting AGC-t carefully, the extra noise is distracting. It is especially distracting when trying to work a new weak one.

I have squelch on 2 Icom rigs and a Yaesu rig that works just fine on SSB. I use it all the time for 6m openings and to listen to the maritime mobile net on 14.300. Works fine!
I guess it must be a difference between our operating practice. I've never found squelch reliable having used a very long list of rigs over the years, most recently a K3, Kenwood TS-590, Icom IC-756 PRO, among others.
A few years ago, I was one of the net control operators for the Pacific Seafarer's net on 14.300. The many signals from around the Pacific varied so much that if I'd set the squelch for a particular level, there would have been a high probability of missing many calls due to multipath fading taking signals below the squelch set point. Setting it lower and noise bursts would keep it open much of the time.
I think that multi-mode HF squelch can be done well but it isn't trivial to make it "set and forget". In my expierience, none of the dozens of rigs I've owned from all manufacturers from Collins forward
Have done it well. I hope when they get to it at Flex that they do it right.
Please give me some insight on how you use squelch and the radio model you use. I have 14 HF transceiver models around here & I'd like to duplicate your experience. Thanks!
I use NR cranked all the way up (with AGC set properly) as a “soft” squelch. Throughout the sporadic E season, I normally have a second panadapter and slice open monitoring 50.125 using this technique and have found the results acceptable.
Bob, N7ZOOn the other hand, when there is a weak FDV signal, the radio will go quiet until you get a successful decode. That's kind of nice, too.
It's nothing to lose sleep over.
