I've got one of the old FT290RII 2m all modes that I'm using as the IF on my transverters. With the SG Lab devices, I can select between RF sense switching and PTT switching, but I now have a DEMI 3c
Hi Sean I use an FT290mk2 with a sequencer. I use the 4th relay to close the PTT and key line and plug the key and mic into a control box where the sequencer relay is in line. I have the key and mic
Thanks for the responses! I got a few good ideas here. I'm not entirely certain why it never occurred to me to pull the Push To Talk signal off of the thing you push...to talk. Way easier than trying
I have been using mine in a similar manner, but I thought someone might offer a better way to do it. I don't use the FT290RII as an IF rig too often. But as I have it wired, when working CW I have to
That might be where being able to flip a switch would come in handy. If I'm reading the documentation right, the DEMI transverters prefer you don't use full- or semi-break in with CW anyway, so you'd
Interesting.. Apparently I'm not the only one working thru these issues. With my Icom radios I like to intercept the PTT line from the microphone, route the PTT line thru a sequencer, then key the ra

...using a foot switch to key everything, either with or without a sequencer, is the way to go IMO, although it can 'get lost' in a Rover environment. I prefer foot switching everything, whether I be

It seems like that method will work, just toss a switch in line for when you want to use CW to ground PTT for the duration. Wire it so that either the switch (or foot switch ) will ground ptt, or the
I've preached that for years!!! Running high power makes it almost a must!! I think Marshall, K5QE has done some presentations on this but you really need to have a breakout box that your mic and key
I've usually been using a modified Realistic HTX-100 as an IF rig for the microwave bands.I removed the rear power module and replaced it with a piece of 1/8" thick aluminum where I placed the power

No - I do it all the time. 99%+ of my Rover operation is done stationary since I can't deploy the antenna mast while driving. When I do work someone in-motion, it's going to be on SSB and the PTT on

According to the FT817 manual, the ACC connector has a pin that goes to ground on TX. It's referred to as "TX GND" but I've seen that described in Yaesu manuals two different ways - one, it actually
I use an FT817 with my 222 transverter.. The pin goes to ground and works fine connected to the PTT jack of my DEMI transverter.. bill, k1DY According to the FT817 manual, the ACC connector has a pin
On my to do list is to figure out if I can safely wire a foot switch (or maybe a hand held pistol grip style PTT switch) in parallel with the PTT lead(s)from the microphone(s). I'm not 100 percent ce
Interesting. I'd be curious in hearing more about this (I also have an HTX 100 earmarked for use as an IF radio, but I ended up using an Icom 735 as the IF radio for my 222 transverter, I already own
You could interrupt the PTT connection from the mic and just tape the mic button down. It's always on but you have it switched lower in the chain. _______________________________________________ VHFc
Support for digi modes is another issue as well. Currently I have a setup where the microphone essentially plugs into the sequencer and the sequencer essentially plugs into the radio microphone input
Yes that would likely work. (I would need to double check that the newer high tech microphones and radios worked ok during RX with that configuration.) 73 Mark S VE7AFZ Aligned Solutions Co. mark@ali
