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

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

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

My 847 has a 2100 or 2300 Hz Inrad filter and want to find a stocker or even wider the narrow filter is not the best when bangin away on 6M FT8 and the like I know Inrad sold a 2800Hz filter, but even

Hi all, Anyone know if the board is still available for the mod adding the roofing filter to this radio? I’ve checked on the InRad site and the filter’s still there but not the board... The

Hi Brian, I don't work 70MHz (yet!) but my ft847 stopped working on 7MHz. No TX or RX. A bit of digging later and I traced it to D3053 in the bpf. Replaced the pair in bpf 4 and it’s working a treat

Thanks Brian -top tip! Hope to see you again on 70MHz soon Steve, M0BPQ

You can repair the encoder: open up the? four retaining lugs on the encoder? which will allow you inside, you can then clean and re-tension the small pick up fingers and reassemble and refit to

I looked on ebay already.? nothing there right now.? I will check back now and then and see if something shows up.? Thanks

Hi everyone, I have owned my FT847 for a very long time, maybe 20 years. It is a UK version that has usually worked on 70Mhz, but has stopped putting any power out recently. The radio goes into TX on

I believe you buy them on EBay. I bought a sub tune encoder for my 847 there a year ago....... Joe. KE9AJ

So I sold my FT-847 to help fund a IC-9700.? The ham who purchased it wanted to return it because he said the AM on the low bands had no carrier when the radio was keyed.? So I took it back as I was

Gary Early model 847’s did not have bidirectional CAT control by design from yaesu and therefore could not communicate with CAT software. YAESU realized this issue and later model 847’s were

I use the RT Systems programming cable (Windows 10) which also works for CAT control using SatPC32. You have to set Menu #37 to 9600 bps for SatPC32 to work. You have to reset Menu #37 to 19200bps ( I

I use my FT-847 for satellite exclusively. I use CAT control for automatic doppler shift frequency control. I use PSTRotator software for that and Omni-Rig software as well. Joe KE9AJ Sent from

Hal I am talking about a straight through to null adapter. It plugs into the radio's com port and the standard serial cable plugs into it KAG! Promises made, Promises kept

What kinda $3 adapter U talking about?? Hal/WB4AEG

Who is using CAT CONTROL and what is the best software for controlling the FT-847? I am about to delve into CAT CONTROL of my FT-847...I have had this rig for many years but never have pursued
