8400 Rx audio disappears

ka9ees

This has happened a couple of times now. Having a conversation on 75m and Rx audio just goes away. It drops at the end of a transmission. It's still receiving. You can see the signals on the panadapter. Restart SmartSDR and it comes right back, but this is a problem. I am using 3.8.19, which was loaded on my computer when running my 6600M.

Is anyone else having this problem?

Hi Ed, I think I would submit a help desk ticket.

Hi Ethan… have you checked the squelch level? It's now activated for all modes on all bands and set by default (I think) for about mid-level. Maybe that's causing the drop outs??

@VE7ATJ_Don I don't know who Ethan is. I have the squelch disabled.

Ed… my apologies… I THOUGHT I typed Ed, but apparently it came out Ethan :-(

Hmmmm… don't have any other suggestions other than as Len said, submit a Help Desk Ticket.

Is the sound completely muting, or just gettting really low? Are you using Headphones or a powered speaker? Is PC Audio activated?

@VE7ATJ_Don Hahaha! NP Don. I just had to dig you a little bit. I am using the same profiles and software I was using with my 6600M. One thing I notice last night was that CAT and DAX weren't shutting down when I closed SmartSDR. So I shutdown those and restarted SSDR. We'll see if that cures it.

I thought I had this cured. With Ken Wells' help I got the rig reset. Built a couple profiles. It went away for a couple days.

It came back. I now have a cause and effect. If I activate the ANF, on my next transmission the audio drops out. Again SmartSDR has to be restarted to get it back.

I would add that information to your support ticket so that the Flex Radio developers can fix it. ( hopefully, sooner than later)

@Trucker they are aware of it. I'm wondering if anyone else has experienced this. It's not happening with my 6600M.

VE7ATJ_Don

hmmmm… it's interesting this is happening on an 8400… I wonder if it might be something not quite meshing between the new hardware and the software….

In any case, great to hear that you can now reproduce the problem reliably. That makes diagnosis MUCH easier :-)

ka9ees

They are telling me both squelch and ANF have to be on, but I only have ANF on. They have assigned it a number and declared it a software defect. I hope that they get it fixed soon.

VE7ATJ_Don

Are they saying ANF and Squelch have to be on to recreate the problem? Or that you must have ANF and Squelch on in order to have RX audio??? In either case, that's really weird, and definitely not the behaviour I see on my ancient 6700 :-) (I have Squelch purposely turned off as I don't wnat/need it) and I don't think I've ever used ANF…

It'll be interesting to see how this plays out. Maybe we'll see a 3.8.20 in the near future, however Mike has already made noises that there's a 3.9 being tested….
