As for my FT-847, I put a resistor in series with both fans to quiet them down. About 50 ohms if I remember right. Never had a problem and it's much quieter. There was a discussion on the group

Is the fan itself making an unusual noise, or is it just on full-speed? It should come on at low speed (fairly quiet) whenever the radio is on. The fan in my 767GX is stuck on full (and

I have fans in my collection of spare parts. This is of no use to you at all, because I am in UK, and you could be in Outer Mongolia for all I know. "Frank" does not give a clue to your location. Take

A metaphorical comparison: Suppose one would consider the complete Internet and calculate that its total capacity is 100x. Then suppose he subtracts all posts about the "FT847 Fan issues" What he then

Where can I find a replacement fan for the FT847 and how to do it? it got very loud as soon as I turn on the transceiver! Thanks 73

Hi Ravi, you are right about the serial number coding. Only, a number starting with a "4" is not older than one starting with an "8" as the production started in 1998 and "8" therefore was the first

Hi, Douglas, Bruno I've used a Serial to USB cable to connect the rig to the Raspberry Pi and the laptop. In both cases, the 'CAT' comes up on the rig, but programs fail to complete the

Hi Ravi, What is there unfortunate about your serial number? As far as I can tell, your FT847 is a november 2004 model which makes it one of the last ones (2005) produced. 73, Bruno

I know that this is an obvious question, but are you using a null modem cable to connect from the PC to radio? I've been using my Ft-847 for 2-3 years with a null modem cable on HRD and have had no

Hi, I have been trying to connect my FT-847 to my RigPi. After a few unsuccessful attempts (many), I then tried to use flrig via a USB (CH340), CAT-847, FTBCAT and FTBASICMMO. In some cases, the

might change out the memory battery while in there since the memory will get wiped

the HF mod it self looks pretty simple since the rig has the AK emergency frequency in the firmware I am supposing that it must have? the band pass filters in place to cover 60M or are we going to

Hi Frank I used the TC1001 adjustment several years ago. No big deal once you find TC1001. I my case I was off about 1700 hz on 432. Got it alot close but without the dropper test equipment, can't

Hi folks, I just found this group and am a newbie to it. I have owned an FT-847 since new from 1999 and would like to know how to open the transmit for 60 Meters. As you know, 60 M was unavailable for

Has anyone tried the "simple" tips of the TC1001 described? Any other method? 73

Yes 250Hz are few but still too many ... Has anyone used the system described here or knows if it can produce problems, if there are other solutions or if this is the

Yes, of course it is. The adjustment is very touchy and if you are not careful or you will make things worse. Sent: Saturday, January 22, 2022 12:08 PM To: [email protected] Subject: Re:

Is the adjustment procedure detailed in the Technical Reference (Service Manual)? Micky K1XH

I am also interested in a solution to this. Mine is off +200 or so Micky K1XH Links: ------ [1] /g/YaesuFT847/message/326 [2] /mt/88602398/1045683 [3]

Your FT-847 is actually in spec. Per the manual the frequency accuracy for the 847 is at best 2 PPM. That translates to +/- 870 Hz at the center of the 70cm band, which is 435 MHz. If you want to
