Cam, why do you want to use a transverter with the FT-847? Is there something deficient with the 2M mode of the Ft-847? If so, seems like it would be far easier to address the problem than to go

You can easily change the FT847 to TX from 144 to 174 MHz, Also the use version goes from 144 to 148, http://f4cqa.free.fr/modposte/tf847/ft847.htm 73 Andrew Sent: 15

Hello all, I'm trying to research the capabilities of the use of the FT-847 with a transverter, requiring the use of 10 meters. The issue may be the requirement for opening transmit to 32 MHz to get

Well the SignaLink USB working great on the 847. 30w out got Japan on my G5RV. 215222 -4 0.1 1104 + CQ JG3LGD PM74 215230 Tx 829 + JG3LGD KJ4DHF FM17 215237 -5 0.2 1104 + KJ4DHF JG3LGD -06 215245

John, There some magic inside that SL to close the circuit to allow the audio to pass to Tx on the rig. I just cannot figure out what is happening to make it work with the Easy Digi board and the pg

Correct; the 847 doesn't do VOX, but I believe the SignaLink does. That was the only way it made sense to me that things were working. The SignaLink was keying the rig via its own internal

Tim, I took up your request to test the keying my radio using a SignaLink and VOX.? My Audio is fed from the SignaLink to the radio using the SLCAB847 cable, plugged into the Data In/Out jack

No worries Spence. Maybe this will help the next new owner of 847.

Sorry about that as I totally got confused. I think the link was generally for anyone? Just provides a simple switching solution. I think I need to go back and re’read this thread from the

Spence, Not sure if your last post was for me or Greg. I can get it to work no problems using the DB9 pins for PTT. I was hoping not to have to build a serial cable for rig and splice into the

Hi Greg, check out John M0UKD’s website. At the bottom of this page just above the comments section is a design that should help. Rig to Soundcard Interface – M0UKD – Amateur Radio

Greg, Thanks for your input. Yes that is the challenge for me. Being able to use the PTT function on the Data IN/OUT jack at the rig to pass the audio from pc to rig without damaging the radio

Using one of the modem lines (RTS or DTR) is likely the "universal" control point for PTT, with a single transistor acting open-collector for pulling the PTT line low.? I would add a series resistor

Spence, Right now I am on Windows as have not found a logbook rig interface program I like using yet on Linux. Tried a couple but cannot get use to the layouts. I been using HRD 20+ years and real

Ooohhh I like that a lot. It’s similar to my first data interface except I used a USB sound card too and patched the transformed into it direct. I take it you are using a 600:600 transformer and

Hello Spence, That is basically what I had to do to use this interface. I had to have access to to the RYS pin on the pc side of the CAT cable. So I just I need to splice into the serial cable and

Is there no way to take the RTS pin on the 9 pin connector and run it into a transistor at the base and use it to switch the PTT line at 0vdc. This way you can still use the RX, TX and gnd pins for

Windows-only application, so not something I can use.? Perhaps others... Greg? KO6TH Spence G5STO via groups.io wrote:
