Stays in Transmit


Steve Norris W5KI
 

Hi.  Looked for any past posts, but didn't find them. 

Before the problem below developed, all control cables and coax disconnected (due to approaching storms), I have a disconnect area outside the house about 20 feet away.  I place the "house" bundle about 2 feet way from antenna area bundle of coax and various control lines to rotor, switches, etc.  SUSTAINED a lightning strike on the densely wooded hill behind me, may have hit an antenna, all 150 feet away.  But you could smell burnt wood, so some tree was hit.  Steep, rocky climb so not been up there yet. 

Results:  Wire damage and blown connector to the outdoor phone cable used.  This at the "disconnected end" of that remote switch run.  No other visible damage.  Inside, besides coming out of the chair from sound/flash from strike, no visible damage.  The lights barely blinked.  Multiple TVs, electronics in the house, and ALMOST all the equipment in the shack is still fine.  (1) The station PC is dead.  YES ... audio, data, etc cables, connect EVERYTHING else in the shack to that PC.  Not the power supply, so the motherboard and beyond suspected.  

But to the point, (2) the backup IC-7000 TX light stays lit RED, no sound out of speakers.   Output is fine.  CW keys.  SSB voice peaks show.  RTTY & FM go to normal power out.  All navigation through menus is normal.  I did a hard reset but same situation after that.  All connectors to the rig removed except for antenna coax -- and key during CW test, and Mic just for SSB test.

Any ideas?  Since all functioning of the unit otherwise looks good, power, processor, etc. ...  I hate to send it off before asking here.  Thanks.

Were cables still connected to the 7K from the PC during the storm?  Which ones?

Is it just the LIGHT that stays red, i.e., can you RECEIVE (even though the TX light is red), and does PTT (or CW break-in) toggle between TX and RX properly? If so, it may be just an annoyance (perhaps the transistor that drives the LED to ground is shorted) and can be ignored.

Some times ago I repaird an IC-7000 with the same iusse, Led TX Red always on.

The owner said me that issue was during a storm with lightning and he used a item link on ACC port. I thought there is a issue on logic board and it was right.

Check on SEND line to ACC port from logic board (CPU), you will find a pullup resistor; I found this resistor opened so SEND line in RX wasn’t on 5 volt but 0 and the result was LED TX on.

Sorry for my english.

Thanks to all three replies.

W3AHL:  Yes, all the in shack cable, inter-connections between rigs, PC, accessories were connected.

KE1B:  No, it is literally in transmit mode.  Red LED and no receive at any time.  PTT as if it is keyed.  FM/RTTY, if selected sends out signal.  CW sends out signal properly when paddle pressed, but not break-in, like semi, always in TX mode.

IW0HEX:  Thanks for idea.  Will work through checking that possibility.

How serious are you about digging into the IC-7000?
Are you comfortable working on little bitty SMD devices and taking the radio apart?
I ask because working all through the drawings and troubleshooting does take a bit of effort.
The schematics are posted here I believe and tracking down the suggestion on the pull up resistor is a good start. 
However if the tracking is not going to be productive...
You could check the voltage on the PTT line on the accessory plug. If it is not high there then it can't be high deeper in the radio.
The same would apply to the mike PTT on the front and back. 
Data socket pin 3, Acc socket pin 3 HSEND pin 7 VSEND.
Pin 9 on the acc is the key line to the AT-180.
I think pin 6 on the mike jack.
The most likely points of failure are where the radio communicated with the outside world.

Thanks JD.  WIth my not so young eyes, hands, etc ... it's probably going to be too deep a dive.  I will check the suggestions made here, including yours....  and decide as I find some of those answers.  I've done some SMD on things like a Steppir controller, etc.  But going too far into the 7000 is likely beyond my comfort range.

Sorry for delay in followup to group on my problem.  Lots of more pressing recovery issues in the shack.

Pasquale (IW0HEX) was correct.  And the other replies that suggested the issue was likely near the point of entry were also.  As previously said, the menu items, power output (by keying on CW), etc are normal.  Since Pin 3 (HSEND) is an input/output control, I applied the +2 to +20 volts (high range) to the HSEND (pin 3) and the rig goes into receive.  All receive functions and sensitivity appear normal.

The .png didn't come through on his original message, so I have asked Pasquale off the group to send me the part number for that resistor.

Not sure I'm up to the task of such small work anymore, but figure some local friends with better skills can help if need be.  Will close out at a future date, when all is hopefully back to normal.

Thanks for the replies.

Hi guys

 

In my case was R1124 fault, as I wrote to Steve 😊

 

In this link, in a local forum in Italy, I have described this problem.

 

You can use google translate for english Language.
