Probelm with upgrade to v 3.1.12

Jim WA9ABB

After upgrading my Flex 6700 to SSDR v 3.1.12 this morning (and it seemed to go well), now there is no signal reception on all bands, except for very weak signals on am broadcast band.  Immediately before the upgrade, it was working fine, and I was monitoring FT8 signals normally on 20 meters.  I reinstalled v 3.1.11 and it did not fix the problem.  I did factory reset on radio and reinstalled v 3.1.12 and still no change in reception.  I also tried different antenna and feedline with same results.  The internal antenna tuner no longer gives a good match(>3:1) to the antenna and was having no problem before the upgrade. I do get a good match (1.4:1) to my dummy load with the antenna tuner bypassed.  The tuner does lower the swr a little more (1.2:1)when used with the dummy load  At this point  I am not sure if it is a hardware failure or something that occurred during the upgrade.  But  it seems strange that everything was working fine before the upgrade. I did not get any error messages or notices during the upgrade.

Does this happen on both antenna ports on you radio? Ant1 Ant2?

Jim, it is strongly recommended not to revert back to 2.4.9 till the maintenance update is released for 2.4.9 witch should be out really soon.

Jim WA9ABB

Yes

Jim WA9ABB

Yes. but it would usually find a match after several attempts. My imain concern is that the only signal I can receive on the radio now is a local am radio station which is very weak now, but usually very strong,

Bill -VA3WTB

Ok it seems clear it has nothing to do with the upgrade, because it did not change after you reverted back to the last version. and It seems clear that there is not a hardware problem, at least not the protection diode. If it were than at least one antenna port would work. Both of them would have to be blown. Work backwards, check your antenna connections and antenna. Set the atu ON BYPASS. and check SWR. Things to start with.

Then you have a good SWR without the tuner?

Maybe loop A or loop B is enabled?

Jim WA9ABB

it was working fine with 3.1.11  till I installed 3.1.12.  Went back to 3.1.11, but still had same problem. So Reinstalled 3.1.12 after factory reset, but that did not correct the problem.  It acts like there is no antenna attached no matter which antenna jack is used. I am betting it is going to need a trip back to its maker.

Jim WA9ABB

SSDR v 3.1.12 opens normally and appears to function except for no received signals.

What about Salvador's question?

Jim WA9ABB

The swr is >3:1 with or without the tuner with antenna connected to radio.  No signals received with or without antenna tuner.  With dummy load swr 1.4:1 without tuner and 1.2:1 with tuner.  It is raining now. Will check antenna connection at outside antenna end and replace coax tomorrow if weather is dry.  But I was having no trouble with the antenna just minutes before the upgrade to 3.1.11.

Jim WA9ABB

No Loop A and B are not enabled.

Jim WA9ABB

Thanks

Jim WA9ABB

The antenna is a 31 foot LGD vertical with 66 ground radials. It pretty much has a high SWR on most bands except 40 meters. Now it is >3:1 on all bands with or without the antenna turner. I will check antenna connections and coax tomorrow if the rain lets up. But antenna and antenna tuner were working normally today till I did the upgrade.  SWR is  fine with dummy load with or without tuner.

Jim WA9ABB

Jim WA9ABB

No the A and B Loops are not enabled.

Yes it was a hard reset. I had to re-enter frequency, mode, and other parameters, etc. from scratch after reset.

Bill -VA3WTB

Jim, if your antenna checks out, I would start a help ticket. It does seem that something happened to the protection diodes for the ADC's. Just my guess. I really can't see how an upgrade could cause this, I think the problem is just the timing involved. But to do damage to those diodes there needed to be a strong static charge or something.

KD0RC

Hi Jim. Just to be sure... The AGC-T slider is not set too low is it? 73, Len, KD0RC

WX7Y

Connect your Antenna to RXA or RXB jack and select the RXA or RXB antenna respectively in the receive antenna choices and see if it receives any better, If it does then the micro TX/RX relays may have taken a static hit. 

Jim WA9ABB

Thanks for suggestion, but AGC-T is OK.

EA4GLI

No problem. I was just suggesting "hoping" it was a user mistake and it doesn't need a trip to the shop... I know for a fact how frustrating that can be.... good luck.

Jim WA9ABB

PS. Anybody know of any good squirrel repellents ?

Sergey KN7K

Jim WA9ABB

Sergey,

Thanks for the info.

There are so many squirrels in my neighborhood, I would have to spend all my time catching them. I was hoping for some repellent that I could put on or around the coax to discourage them. Thanks for the info, the catch and release trap would work if there were only a few, but way to many to catch them all.
