A real handycap for DXers

Joe

Listen to DX on slice A then decide to call on their QSX freq placing TX on slice B. All is good. But now go to another band momentarily to check a spot and then return to original band. TX IS NOW ON SLICE A and your calling on top of the DX and all the police men are yelling up up. This really stinks! The slices should stay as they were

I think it's okay the police yell - UP, that doesn't stink...

I tried this on 6500 but can't duplicate.  When you check a spot, which slice did you use A or B?  Tried but but can't duplicate.

You can use XIT for now or use 3rd slice to spot as interim solution.

Good Luck and DX

Isn't that purely the behavior of the logging/dxcluster software. Hrd behaves 'eeirdly' and tries to use b as rx and a as the qrx freq.

Joe

It happens when momentarily jumping to a band with a single slice open so TX is on A. Going back to the original band with 2 slices and TX WAS on B now TX is on A. Flex 6700

Joe

Nothing to do with the cluster purely a manual adjustment between bands. No CAT even connected

Are you sure? I've had my 6700 for 2 years & it doesn't do what u r suggesting? Which Flex do you have?

My 6300 behaves as Joe states. Not what I would expect or embrace.

Joe and/or Dan... Would you please describe the exact steps you take using SSDR to do this? Please be very specific. I'd like to try to reproduce what you're seeing. Peter K1PGV

That sounds like what I'd expect. Why not use one of the other six slices to do the checking?

Joe

It is pretty simple  1. your setup for split operation Rx on slice A and Tx on slice B lets say on 15M.
2. You change bands by clicking 'Band' from the upper left menu and select 80M. But only 1 slice is open on 80 and TX is Slice A. 3. Now change bands back to 15M ...all is the same as you left it frequencies are the same, bandwidths are the same except Tx is now on slice A.

That is certainly not what I would expected while SDRs are a different radio architecture a legacy radio wouldn't reverse TX/RX on VFO's after changing bands.  I don't recall that happening prior to 1.5 maybe I never noticed it. I get that slices and VFOs are a different paradigm but makes operation very non-intuitive. If you carry it further ...why doesn't the modulation mode or bandwidth change?

And ya you could open another slice but just something else to remember that sets you up for Tx on the Dx freq. and If you say you never transmitted on the Dx calling freq your a better man then I am. I would just like to limit the embarrassment

This has burned me on several occasions.  I had the band police all over me a couple times because of this.

Perhaps I am just unlucky, but it seems now that every time I turn the radio on and tune around I hear some ham(s) yelling and complaining about some other ham. Some of it is malicious like the SSB group that purposefully placed their new roundtable knowing they would bleed into the well-established AM frequency on 3885 kHz. What they didn't know is that with the Flex, I can pull the upper filter skirt in and eliminate any trace of them! I can't do that with my R390A! 

peace and harmony ....

I think this is definitely a bug. I'll add it to our issue tracker.

If I understand correctly, that once you set up split, if you switch to another band, then come back the split is off?

I've worked knob & button radios that also do this.

Premise is if you moved bands you are unlikely to want to work a cross-band split while on the other band, and that the rig cannot know what your intentions are when you return to formerly split band, so the rig defaults back to RX/TX on one freq.

Or is it something else you're seeing?

Steve no you don't understand. You have two slices. Rx on A and Tx on B. go to another band then return then Tx is on A and Rx is on B

I have had a 6700 since the "beginning of time". I can confirm the behavior that Joe describes. Surprised me greatly while chasing TX3X. The police came out in droves.

I am glad Ed.G has added this to the issue tracker. It needs to go away.
