New SSB Squelch function
Locked
 
|
I downloaded the latest beta with the squelch and tried to set it up, but I wonder if
there is something about it that I don't understand, or need to adjust differently. I was hoping I could basically set the squelch with the RF/SQL knob on the front panel...crank it all the way clockwise for full on with no squelch (for trying to detect weak signals in the noise) and then back it off as desired to set the squelch threshold for the strength of the signals required to break the squelch. However, in my setup it seems to function just the opposite! The squelch is always on when the RF/SQL control is fully clockwise, and when I back off on it, it OPENS the squelch as some signal level greater than the no-signal noise level. How do you adjust it to listen with the RF gain fully open so you can hear the noise level? Right now, the only solution I have been able to find is to disable the squelch entirely in the CONFIG. MNI TNX for any guidance! VY 73, Lance -- Lance Collister, W7GJ (ex: WN3GPL, WA3GPL, WA1JXN, WA1JXN/C6A, ZF2OC/ZF8) P.O.

Lance,
You have your choice of either an RF gain control OR a Squelch control (but if you do not have the subreceiver, you can have both). If you choose to have the squelch control, then the RF gain can be handled by using the attenuator and the preamp, and the AGC will also work to limit the RF Gain when listening to strong signals. All Squelch controls I have used conform to the way the K3 Squelch control works - it controls the level at which the squelch opens. Think of it as being numbered 1 to 9 (like the S-meter scale). When at position 2, signals greater than S-2 will open the squelch, but if set to 9, only signals above S-9 will open it. The numbers I have used are only for illustration, there is no exact correlation that I know about. If you do not have the subreceiver installed, you can set the CCONFIG menu SQ MAIN = Sub Pot and you can have the RF gain control on the main knob and the squelch on the sub knob. Yes, the same is possible with the subRX installed (set both SQ MAIN and SQ SUB to Sub Pot, but you then have no RF gain control on the sub. 73, Don W3FPR Lance Collister, W7GJ wrote: > I downloaded the latest beta with the squelch and tried to set it up, but I wonder if > there is something about it that I don't understand, or need to adjust differently. > I was hoping I could basically set the squelch with the RF/SQL knob on the front > panel...crank it all the way clockwise for full on with no squelch (for trying to > detect weak signals in the noise) and then back it off as desired to set the squelch > threshold for the strength of the signals required to break the squelch. > > However, in my setup it seems to function just the opposite!

Don - A couple of minor clarifications:
1. If you dedicate the Sub RF gain knob to adjust Squelch, you get a combined RF gain for both RXs on the main RF gain knob. 2. If squelch is fully counter clockwise, it is always open with no threshold. This is all covered in the latest f/w release notes and the presently-shipping K3 manual. 73, Eric WA6HHQ ----- ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Thanks for the clarifications Eric.
I do not have the subRX, so I "assumed" and we all know what that does. You are correct about the SQL knob at zero. I do mentally relate it on a relative scale basis to the S-meter - the higher it is set, the stronger the signal must be to open the squelch. 73, Don W3FPR Eric Swartz - WA6HHQ, Elecraft wrote: > Don - A couple of minor clarifications: > > 1.

AHA :-) I went back to it yet again and finally found the SUB POT option at the
end of all the SQ MAIN number settings :-) Things are working just GREAT now! I guess I just need to be a little more adventuresome in hunting for some of these settings! MNI TNX for prompting me again to tackle this and go in search of the proper setting option!

Lance,
Wayne is working on the issues and the latest release that I have tested looks good. Wait for the next beta and I think you will find it more effective. 73 Dan
