Re: Couple of questions

 

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 AM/SSB

For the past 20 years I have used this home built interface based on the following which I think credit to VA3DH who came up with the design originally?for W95SSTV?software, on several FT-847's which gives all mode data :

In improving the PTT switching and?making electrically isolated totally radio from?computer you could adapt and use a 4N25 optocoupler in?place of the switching transistor.?

?
I hope this is of use ?

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 for some reason the radio goes into TX mode. Have to look into that. Question # 1: Can I use the PACKET jack for digital modes such as FT8 or AFSK RTTY? Or is it strictly for packet operation?

I'm trying to get into the service menu to align the shift control as it sits at about 1 o'clock when both USB and LSB have the same tone. I've tried the UP/DWN/FAST on the mic while turning on the radio but the regular display just keeps coming up. The up and down buttons are working fine on the mic, but when I press the fast button, the FAST icon does not appear on the screen. Possibly a bad wire inside the mic?? Should the FAST icon come on when activating it from the mic?

Everything else appears to be fine, showing full power on HF, 6 and 2m. My 440 antenna has a PL259 on cable, working on getting an adapter!

Any pointers appreciated.

Thank you,
Max VE3TMT
