Hi all,
My first post in hopes Im posting to the right format. If not please guide me in the right direction. My problem is this: Im using the SCU-17 digital interface with my newly acquired 817ND. I am trying to get it to work on FT-8. Im using WSJT-X for the software. I am able to get it to receive no problem. I also have the cat control working as well. PTT seems to be working but my radio is not showing power output when it is keyed up by WSJT-X. It seems to go into transmit but the meter shows no power output. Im sure it is just a setting in WSJT-10 or possibly I need to set something in the 817 menu that I am missing? If anyone else is using the 817 with the SCU-17 and WSJT-X, I would like to see what your settings are if possible.
Thanks-Bob-W0YBS

Re: Windcamp FT817 CAT/PTT/Phone adaptor
if it has the ptt, it could conceivably work to an extent but usually there is a sound card in the mix somewhere and some kind of vox circuit to actually trigger the ptt on transmit.
Hi All
My first post (question) on the new Group!
I bought myself on of these 'Windcamp FT817 CAT/PTT/Phone adaptor'? (
and I was wondering if it would work as a digital mode adapter for connecting the Ft-817 to my laptop.??
Has anyone used these before and know if they would work and how to set them up?
Thanks in advance

After the first subscriber approval I've processed I've got back to first post moderation.
There is no way for me to tell if a subscriber is a spammer or not until they post for the first time.
There may be a way for subscribers to include additional information in the request, but for now this approach makes the most sense to me.
The end result is that list members won't be bombarded with spam. If a spammer attempts to post I'll just remove them.
Mark.

Re: GPS lock the FT-817 for transverter
Bill, I¡¯ll bet you (like myself) wished the FT-817 had a tighter 2m pass-band.? We don¡¯t need to hear pagers and other out of band crap.
Keep a watch on the new ICOM QRP radio.? Perhaps it will do what the KX3 failed to do, surpass the 817.? It does have 2m and 70cm from the start. ? ? Vy73 - Mike - KD5KC. El Paso, Texas - DM61rt. SOTA W5T-Texas Association Manager. NA-SOTA info is at:? ? ? ?

Bill, the 818 was a big nothing burger.? It was mostly because some of the parts in the 817 became unobtanium.? The specs are pretty much the same.? They did include a better battery, but still not as good as the after-market batteries available.? They now include the TCXO-9, but increased the price to reflect that addition.? Unless you are running transverters at micro-wave freqs. the TCXO-9 really isn't necessary.All the hype preceding the actual release was amusing.? I imagine some were totally let down after the release? I didn't let myself get carried away, "wait and see" was my thought.
In my opinion, the 818 is worse than the 817.? They added a 6-watt high power.? Do the math and you'll see the difference between 5 and 6 watts is very little on the air.? But it is a 20% increase in battery consumption.? WHY? Furthermore, to make room for the 6-watt level, they removed the 0.5 watt setting.? This 1/2-watt setting was wonderful for those of us who run transverters.? WHY again? There are many many many WX radios that will run for days on two AAA-batteries, the 817/818 would be a waste in that respect as the RX consumption was not improved.? My vote is for tighter passbands on 2m and 70cm, better for those of us who do weak-signal V/UNF from noisy mountaintops.? There is no award for worked all pagers. The more recent news about the pending new ICOM may actually do what the KX3 failed to do, that is to compete with the FT-817 across the board.? Many of us are watching and waiting....?
