Greg, Thank you very much. My FT-847 is in the serial number range of 8K15xxxx so it is well after the 8G05xxxx mentioned in the link you provided. 73, Bill, W9MXQ Sent: Wednesday, July 06, 2022 11:58

The issue was that the earlier version of the radio had a 1-way CAT interface (computer to rig only). See: https://mail-01.amsat.org/archives/amsat-bb/200811/msg00082.html Greg KO6TH William Shadid

Don't know if every radio ever made has the same 'feature' but... Tried to contact the ISS during field day Uplink 145.990 FM Downlink came out to around 437.962.3 FM clear receive signal. As soon as

I am still not clear on the serial number when the CPU on the AF-CNTL board was changed. I've tried to search for it but no luck. And for that matter, what was wrong with the initial CPU. (I admit I

What Tom said. It's the way many HTs are keyed as well. I built a cable harness roughly similar to what Ian described, hooking it to a Raspberry Pi 4B with a USB audio dongle. The PTT side of things

Hi Ian, Yes I see in the manual now you have to use a blocking capacitor on the TX audio line. That should be easy enough to do. Coming from a Kenwood TS-850S, I owned a couple of FT-990's and a Mark

Hi Max From what I remember if you ground the audio out (the tip) this then enables PTT on the data port. If I am wrong anyone please feel free to correct me I hope you have great fun with your FT-847

Hi Gerald, The CPU on the AF-CNTL board must be replaced.? Some service-centers got them from YAESU and did replacement on warranty back then. I got my CPU from UK and as I recall the cost was about

Good morning guys, I got may radio when it was first introduced and never found out about the update to it. Does anyone know who or if the digital upgrade part is still available and is it worth it? I

Thanks Tom, Just saw that! Max

One page 16 of my manual in the section re "AFSK TNC Connections". Check the diagram showing a 10uf cap and 2K ohm resistor connected to the AFSK TNC. Easy to build your own if you can obtain the

Ian, Greg Thank you for your responses. I don't see anything in the manual that mentions the PTT keying on the DATA IN/OUT jack. Am I missing something? How do I go about separating the PTT line or

Congrats on the new rig! Great radio, but it has it's quirks. You've run into my #1 peeve. There are two jacks on the back for interfacing with digital stuff. The DIN port is for VHF/UHF packet, and

Hi Max Regarding using data on the FT-847 its a little bit complicated compared to more modern transceivers. As a rule of thumb you use the Packet port for FM based operation and the Data In/Out for

Hello to the group, Just took delivery of an 847. Great radio. I'm just in the process of getting everything hooked up, CAT, digital modes etc. I plugged my signal lines into the DATA in/out jack and

Thanks Vic. Something in my head says I should have thought of that myself. Dennis VE3XC

Hi Greg, check the Group Files section, there is a folder there - FT847 Mods - in there you will find a Yeasu datasheet on frequency mods, it extends the range of the set. i uploaded it quite a while

Out of band mod? I wasn't aware that there were any such mods for the radio (e.g. to get it to Tx on the WARC bands)... Greg KO6TH Dave K?EKL wrote: Thanks for the replies. I have not yet fully

Thanks for the replies. I have not yet fully unpacked the truck from Field Day. When I do bring the radio back into the shack I'll try a full reset, try transmitting on freqs across the 80m band and
