Hi Rob, You need to key the rig with the TRS jack, not the DIN. The DIN heads over to the FM world, and I don't recall it working with the HF SSB modes, though I could be wrong.

Thanks Greg & Tom I think I understand but I still cant get it to work. I was only wanting to use the 847 on 2m FT8 and was wiring to the 6pin data socket only. The soundcard USB Data mode cable I

What Tom said. The 847 is centered in the "uncanny valley of engineering" with its handling of PTT. Too smart, and not smart enough. It apparently tries to choose the audio

Not having AF out connected to the tip would cause the problem you are seeing. I have a FT-847 running FT8 using PTT multiplexed with AF out per the manual. 73, Tom K6EU

Hello again Rolf......yes, I use the interface cable (forget it's number now & its hard to reach - but its the one that MFJ makes for the 939). The only possible drawback with the 939 is that it has

Hi Mike, thank you for your reply. Short question, do you use an interface cable with the FT847 or not ? 73 Rolf, DC1ZZ

Hi Nils and Joseph, many thanks for the answers. Actually I try to find an automatic tuner with interface cable.And yes, the FT847 is no longer in production. 73 Rolf, DC1ZZ

Hi Rolf I used an LDG YT847 with my FT847. It was truly plug and play, just connect the RF to the radio. I worked very well with my HF9V antenna. I have since sold mine and I don’t think it is

Hi Rolf, I must confess that I haven't read the manual for the 929 until today... The version seems to be 1006 and the age of the unit is unknown to me since I bought it second hand. The only

Hi Nils, thank you very much for the reply. I used the MFJ 929 myself many years ago. At that time I had noticed that the firmware version in my device was a very old one and from the selection of

Hi, I use MFJ-929 on all bands 160 - 10 meters with a multiband vertikal Sandpiper 10. Have worked abouit 3000 QSO so far. Works very well for me. /Nils SM7DVO

Hello, I am looking for an automatic tuner (no FC20) for a FT847, which works well with this transceiver. Do you have a recommendation for me ? Many thanks in advance. 73 Rolf, DC1ZZ

not exactly the same question but I run the TRS connection as my only audio in/out and key line for HF/VHF/UHF, lots of FT8 during the VHF/UHF contests I also run a USB serial thingy and let it trip a

Hi Steven, Yeah, I'm not sure what the designers of the 847 were thinking when it came to digital operation. It appears that they tried to have the transmit audio path follow the

Hello, I am having a problem originating a message. Before I waste anyone's I would like to ask the following question of the group before proceeding. Is there anyone who has successfully installed

Hi everyone, I am desperately searching for a replacement plastic knob for the Mic/RF control.? I am told that the Yaesu part no. is RA0065300A.? I have enquired in loads of places, and everyone is

I have for sale a Yaesu FT847 HF/6m/2m/70cm all mode transceiver in very good condition. This model does 100 watts on HF and 6 meters, and 50 watts on 2m and 70cm. It also does full duplex for

When I first got my 847 I was using a 20 amp power supply. My radio kept shutting down unless I turned the power down. Couldn't figure out what was wrong until it dawned on me that the rig needed more
