Repeater shift stays active after changing mode from N/FM. v1.4, F6300

Steve Walker

Earlier today I'd been up in 10m FM working a couple of repeaters in NFM with the default 100Khz drop in TX frequency active. Then today I popped down to 40m with the same slice active, changed to USB and put a couple of calls out - and noticed that I was down 100Khz on the waterfall!. There appears no way to change it without changing mode back to N/FM and clicking "Simplex". I have not seen anyone else report this, and wonder if this is by design or expected behaviour. I have had several classic radios that when you leave the mode which was working "repeater shift" and return to say USB you get RXf=TXf it would be odd to have a non N/FM mode working a repeater on HF ...

Fully reproducible and you get no indication when you leave N/FM that anything is "on" in the way of a shift in TX frequency.

Steve,

I do not see that with my 6700.

Steve,

Thanks for the report.  When you went to 40m, did you press the 40m Band button, or just tune the Slice to 7.x directly?

Hi Eric,

If I choose the slice I am using and use say HRD to shift the band or to tune to the band myself entering the freq in the panel and/or click the 40m button then say choose LSB (if HRD has not already changed the mode) it persists the shift. Attached are some shots.



10m FM with SLICEA



I set a -100Khz shift which is obeyed fine. I then change mode...



And drop down to 40m ... and tune up on LSB and we see the shift is remembered.



Even clicking the band button does not loose the shift, only going to N/FM and then removing the shift or clicking simplex does the slice behave.



Does that follow OK? If you use an external program like HRD to tune from say the cluster then you get the effect immediately!

Steve,

Does the shift persist if you change the slice frequency after you change modes? 

Steve Walker

Yes if I am on 10m and change from FM with -100Khz to USB / LSB then it remains.

If I then tune to another band by entering 14.200 then it is lost however the screen shows it as active when in fact it is not. The TXf = RXf even with it shown otherwise.

This was done by going to 10m 29.300 then clicking FM, '0.1' shift, '-' then TXing, changed mode to USB, retuned to '14.250' by tying in the slice. Then you see that the first attempt without retuning shows the offset but does not TX down by that amount but RXf = TXf. If  you move tuning then it corrects (mouse wheel up 1Khz) and you have the shift back.

Ed,

A better test. 14.250 FM with a repeater shift of -100Khz. TXs on RX freq:



Change to USB



Normal looking simplex TX...



Change back to FM and shows the -100Khz repeater shift as active, however TX is RXf, change the wheel up 1Khz and voilà!

Steve,

Thanks for the info.  I think we know what this is.  I have written this up in Issue #1860.
