Tim,

I have had some problems with GEN, WWV and 160M bands, I hope to Doc the problems in the next few days can I send you what I find, I have had problems when I open three pan adapters with GEN 160M and another band then close the pan adaptors and go back to 160m single pan adaptor I have had various little problems.

I do need to know the sequence of events and a description of the failure so we can reproduce it.

Tim,

Here is one of the sequences I use.
20M 1st pan adaptor
160m 2nd pan adaptor
WWV 3rd pan adaptor (15Mhz)
17M 4th pan adaptor
now close pan adaptor 4,3,2

Open 160m on pan adaptor 1
Open WWV on pan adaptor 2
Change frequency on pan adaptor 2 to (10 MHz) via the slice

Now go to band on pan adaptor 2 and select Gen Band

Let me know what happens

So are you saying that if I have the WWV band selected and change the frequency to the WWV Stack it changes the Stack for the GEN Band?

There is no WWV "stack" or collection of frequencies for any of the band buttons; there is only a single frequency assignment associated with each band button on a per panadapter basis.  That particular slice frequency is "remembered" or persisted, so after selecting the 20m band button you tune slice A to 14.185 and then click the band button to go to a different band, when you click on the band button again to go back to 20m, it will tune the slice to 14.185.

If you manually tune a slice out side of a ham band (frequency range) or off of 15 MHz which is associated with the WWV band button, then you are by default in the GEN band and that slice frequency associated with the GEN band will be persisted, again on a panadapter basis.

Thanks Tim, now a lot of things that have happed as I move around the frequencies are explained. I check a large range of frequencies outside the HAM bands using the Flex and my Drake TR-7 as General coverage receivers.

Thanks again for you help Tim.

Regards,

No problem.  Like I said we are looking into the entire class of behavior to make it a bit more predictable in a future version of SmartSDR.

I have some wide band noise at my QTH and like to open a single panadapter as wide as possible to look around the whole tuning range of the radio. Usually after this a band change will lock up the software and I have to reboot the radio and restart SmartSDR. Suggestions?
