I am having the exact same problem. Packet works fine on FT-7900 vhf. Put the same cable into Packet Port on 847, keys up fine, tx fine, signal but no audio heard on another receiver. My understanding is that the Packet Port is for vhf/uhf packet which is what I want, and that the data in/out port is for HF. So you are not alone John. Maybe we can both get some help with this.? 73 de Dennis VE3XC

I was wondering if you are using the DATA in/out port for the signal instead of the Packet port.

Or maybe, the jumper block inside the signallink is wired slightly different.

Just a thought.

I have a Ft-847, signalink, and using agwpe but I am having problems with getting mine setup for FM packet.? I have everything working and confirm it works on my FT-8900 which successfully sends packets audio but I can not get the 847 to pass the transmit audio. When I send a beacon the signalink keys up the 847 but no audio is passed through to the radio. The 847 will receive packets and it will pass computer audio from other sources through the 847 and key up the radio but no audio. I also did see the renaming the USB audio names and like I said it works very well on the 8900 but I'm lost. I did try playing with the tx delay in agwpe but still no change. So to summarize: * 8900 No issues and works as normal *847 -Keys radio but no audio for tx with no changes to setup. -Does key and pass system sounds when set to do so. I appreciate any help that might solve my issue or special settings needed to get the audio to pass.

Unfortunately my soldering iron packed it in so I haven't been able to remove that 2nd PC board the crystals are mounted on.? Notice the braille-like bumps on the ends of the silver cylinders.

That is unfortunate...?? I hope you can make a claim with mail service.? I wonder if it is at all salvageable

Guilty!? My parents could tell you horror stories (for them) about me taking apart things when I was very young.? :^)? And that's only the things they found out about. Hihi!

But the story about the filter is that after looking for two years in Canada, I found only 3 but of the first two, one wanted Paypal only (which I don't do), the 2nd one I missed by a few hours, 3rd one: success! ....until it arrived in the mail totally crushed.

You must be one of those kids that always has to take things apart to see how they work
HI HI

Ever wonder what the inside of a Collins mechanical filter looks like?

Check your power supply connections. Loose connection are OK during
receive, but during transmit, you will be a voltage drop resulting in all
kinds of bad things happening including relay chatter.

Hello All
Has anyone had either of these 2 symptoms on their 847?
When powering up or occasionally during operation to chatter or flicker
causing you to restart controller software.
I have had it, now, several times. It sounds like relays trying to make
contact.
If this has happened, is there a fix?
Thank you

Closest I've had was the in-line fuse overheating, corroding and making poor contact. Mine were the cartridge fuses, not the spade terminal ones which are a lot better.

Well somehow I managed to loose/misplace one of the 2 smaller rubber button inserts when I had the display unit disassembled for other repairs.? This was the Tuner Button Rubber insert in the face plate.? I was wondering if anyone has a parts radio that would be willing to sell me a replacement rubber part.
Thanks, Will - N7IPY

Q1134 can be found on the backside of the board near connector J1028.

Hello.?

?I have a faulty FT 847 serial number 6G070383. The problem is Q1105? CPU of the AF-CNTL board doesn't get is 5 supply.
According to the the service manual, this voltage comes for 5 volts regulator Q1134, LM8705ua chip.
Unfortunately I? cant find this chip and all the relevant components on both sides of the board, so I cant trace the fault.
So please, if someone has any info about this, please let me know.

thats a good idea Mike??
almost cheating??
but it wont work currently as the CAT circuit is poofed on my rig
no life on the lines at all??
I have the MAX232 chip and the muxer chip on hand, for when the day comes and 6M isnt open??
??
and after more thought??
that is a excellent solution, as I very seldom move off of my TX freq of favor??
and even when doing voice on 2 and 6 that wont really bother??
so till I find a filter I am in business

I know Inrad sold a 2800Hz filter, but even if it was still available I wont be paying $180 for it
if anyone has a stocker? and someone need the narrow in mine?

There are two SSB filters...? One TX and one RX (owner's manual page 95).? Are both of yours narrow?? If not, you could try swapping them.? Using SPLIT or FAKE SPLIT in FT8 should keep your TX signal inside the filter passband on transmit.
