Anyone ever tried remote HF CW operation?
In our 80's, we are downsizing -- dramatically.? Will be moving from 2,500 sq ft house we built 17 years ago to 1,200 sq ft apartment.
?
Our son lives about 10 miles away from the apartments on 5 acres with big trees -- perfect for one or more dipoles.
?
Has anyone ever tried -- or is anyone now using -- remote operation?
?
Here's a link to a presentation about remote operation.

?
Seems as though I could put my FT817 or FT857 at his place, get another 817 or 857 for the apartment, and link them remotely over the 'net, and operate CW -- which is all I do anyway.
?
Anyone tired this, or, doing it now?
?
Would it be as simple as a laptop and a rig at each location?
?
Thanks

Closing the loop and following up. I went the route of opening the base of the mic and running a wire from the cct board to the FL110 Pin 4.
Simple job, works perfectly.?
The only thing i MUST remember is only turn the amp on when I am on HF!!!!!

Hi everyone
Some great? answers here that seem to have given me the info I need
Yes its the RF sense switching thats causing the issue - I much would rather use a ptt sensing myself.
As suggested , I will rig up a connection from the ptt pin on the data or acc port to pin 4 on the amp power connector.?
Due to a slight physical disability i find fine soldering an extreme challenge.. so working with those old din connectors is not a chore i look forward to. hihi!?
So, as I use an MD1 desk mic, it might be easier to tap onto the PTT line on its much bigger connector or inside the base itself?
Alternately, I could make a big? button connected to pin 4 on the amp that I manually hit? just before or after i press ptt each time, if i want high power this over.
Stick it on the mic base next to the PTT.
Great stuff all! Great bunch of hams we have using these brilliant tiny boxes
Hopefully we can have a 817 to 81x chat soon!
THanks for this?

Jem,

So it is best to use a PTT keying line ?so when you press the microphone, the FT817 is in TX mode with red LED on, and the FL110 is in TX mode with red LED on and then you speak which then produced RF. ?The FT817 finals see a proper load.
?
By using RF sensing, the FL110 is in receive mode, you speak and transmit RF to the amp which senses Rf, the slow changing relay in the amp switches from rx to tx, that slow changeover means for a small amount of time the FT 817 finals don’t see a proper load and can be destroyed.
?
I have been using my FT817 and FL1110 for over 20 years with a direct PTT line without any final damage.

Hi Jem,
?
please download service manual to adjust delay time and RF sensing sensitivity .
?
WARNING -
Just a word of warning when uses this amplifier with a FT-817. Used in the RF detection change over mode, this set-up lasted about 5 min before the '817 PA module blew!
I guess the change over time of the amplifier relay was enough to leave the '817 output unterminated, and with no effective high SWR protection in the 817, caused the PA to fail.

Looking at the schematic could vr201 alter the hang time?
|
If the rx tx switch is relay activated it may be possible to alter the switch time by using a different capacitor depending on the circuit.
I have a 70w amp for my 817 which has an electrolytic which feeds a transistor controlling the relay closure, opening is instant with 1w rf. Varying the value of the cap alters the close time of relay.

Hi Jem,
As convenient as it might be to use RF sense for PTT I think it falls far short of satisfactory for SSB operation as you have clearly demonstrated. I reckon it would be much better to take the PTT line from the accessory socket on the radio and interface it to pin 4 on the amplifier accessory socket to reliably switch it to TX.?
Jem,
It sounds like you have VOX turned on.? It is found on the front panel menus.? Access by pressing the F key and use the select knob to move to menu 10 VOX.? Pressing the A key turns it on and off.

Hi?
I was wondering if anyone has any tip on this combo
.
it seems to work ok but as the 817 is so low power , the T/R switching on the amp keeps cutting in and out on ssb with the audio.. When Im at full voice its fine, but on pauses as i take a breath (yes I do that!) it? goes to RX again,, meaning every over is on/off/on/off and choppy. I need faster tx/attack... but longer "hang time" to stay in tx after i shut my pie-hole a few seconds.
Does anyone us has used this combo know if there is an adjuster in the amp or mod for this.??
Any thoughts?

Re: Solar Generator for portable power
Yep!? Example, attached.? This is an "AC Anywhere" 140w inverter,
the kind you plug into your car's 12v Accessory outlet, driving a
60w incandescent bulb (a non-reactive load), but all the modified
sine wave inverters I've tested look pretty much the same.? The
inverter in the HOWEASY should be very similar.? All those edges are
radiating a bazillion harmonics.
My first pass at an off-grid solar / battery setup for my Shack
included a 1kw modified-sine wave inverter, only because I got it
free.? I was figuring a few birdies that I could work around.?
Nope.? It wiped out the ENTIRE HF spectrum, wall to wall, 80 meters
through 10.? I swapped that out for a Victron pure sine wave unit,
and all is peaceful and quiet.
Your switching to a simple battery setup, backed up with solar and
an MPPT controller is perfect for what you're doing.? It might be
worth getting a small inverter, preferably a pure sine wave unit
since they've come way down in price recently, just as a backup for
around the house if the lights go out.? Run a LED / CF lamp, charge
your laptop or cell phone, whatever.? Good Ham Swap item to keep
your eyes open for.

As long as you understand that a modified sine wave is really just
another form of a square wave. I've put them on an oscilloscope a
number of times.?

Thanks to all those who replied on this subject.?
?Lots of good advice from practical experience.? ?Yes,
Greg the HOWEASY has a modified sine wave inverter.?
Based on what I have learned I am abandoning the idea of
using a small, cheap solar generator.? ?I already have a
folding 60 watt solar panel with MPPT controller and a
suitable small 12 volt battery charger.? ?I will simply
but a small LifePo4 battery in the 10 amp hour range and
call it done.

Re: Recent final board price / availability?
I hope you get them and let us know how it was to replace.?

Re: Solar Generator for portable power
I’m using a 5ah expert power lifepo4 battery. I am yet to have any difficulty doing a pota activation with it. I’m guessing the longest has been about four hours. I have not felt the urge to tag my solar setup in on it at any point.? When I am running QRO with an FT-891 I have a Chins brand 12ah lifepo4 battery. I run the radio at 40w most of the time and the battery lasts longer than I do. I used to run it at 100w most of the time and the battery was good for 3.5-4 hours. Adding a Bioenno 60w folding panel to the equation, it’s pretty much an all day situation. I have been doing jamboree on the air for the local scouts for the past few years and for that I have been running 100w. Last year we kicked off at 0830 and shut down at about 1830 with no difficulties with power at all. That 60w panel keeps the battery topped off well. I have, so far, not felt the need to go out and get one of the “solar generator” setups. They don’t fit in my backpack and are too heavy and bulky to carry in my hand.?

I also use a Bioenno LiFePO4 battery (20 Ah) for portable use. ?I top it off with the supplied AC charger at home, and I’m good to go for hours and hours with my FT-818. ?Probably 5 lbs which is fine for picnic table operations at parks.

This works for me, as I do not need the AC inverter provided by “all-in-one” power packs. Bioenno also sells portable solar panels and charge controllers that may be cascaded in the field.

Best of luck in your search…
