I couldn't find the answer in the User Manual so I asked ELAD Support.. Here's Vianneys' answer" "The impedance matching range of the DUO-ART ATU is about 6 to 1000 ohms up to 10 meters, and about 16

I can't think why not, but much better to ask a foolish question than to do something stupid !! Is there any reason why I couldn't (or shouldn't) connect a dummy load to ANT 3 connection on the ART-60

Brilliant! I don't think you can class yourself as a beginner any more Tom. Neil G4DBN

I guess I should point out that I did test the connection, but couldn't test it beyond my Licenced power limits. I'll get my "G0" friend to visit tomorrow so we can try it at 100W+

Hi all, Well I've just come online after successfully sorting out my cable, only to find that Vianney has visited. Thanks for your effort Sir. And thanks too, to Neil and Heinz again. I started from s

I see there are FT817 ACC to USB serial adaptors for sale which have an RCA phono inline socket for the PTT line from the mini-DIN ACC plug to deal with this type of use-case, but I can't see any with

No problem. I apologize that it took me some time to provide this information. We have made up, time ago, a custom interface with : - a schematic similar to the one of the CT-62, - and the pin 8 from

#duo-art #ft-817

If that yellow wire is incorrectly shown in the drawing as connected to pin 8, then ignore everything I suggested about unsoldering wires Tom. It certainly seems to be labelled as "5" in the drawing w

#duo-art #ft-817

My understanding of the FT-817 user manual is : - PTT signal on the DATA connector is an input, - TX GND signal on the ACC connector is an output. Apart from that, only the ACC connector is needed to

I think I have learned more about ham radio in the time I've owned these FDM-DUOs than in the previous 40+ years of having a licence. Every day I realise just how little I know about everything. Every

As i said, HAM Radio Operators Life is always a Learning Curve. I was on the wrong Path. TX GND is the right way. 73 de Heinz-Juergen

#duo-art #ft-817

And sometimes..... I was wrong. Did a little research and yes, Elad shows it right. Mea Culpa. Mea Maxima Culpa. TX-GND (Pin 2) to GND (Pin 3) on the ACC Port is used for keying a external Amp. I thin

#duo-art #ft-817

I could be wrong, but we could both also be right as I think either method *will* work, but it just seems a little less hassle (and, to me, *slightly* more correct) to use the TX GND pin in the ACC se

#duo-art #ft-817

And this, my friends, is why I felt the frustration in the first place, LOL. I now have two very clever and highly knowledgeable Ham Operators who cannot quite agree on the right solution. So how is a

#duo-art #ft-817

I also didn't own a 817 and i would do some measurement before soldering a cable. PTT to Ground should work when i read the Duo-Art Manual correctly. 2/3- PTT in/out3.5mm jack connectors. PTT in: Inpu

#duo-art #ft-817

Several schematics I've seen use the 817 TX GND as an output to key an external amplifier. PTT is an input, which just happens to get pulled to ground when you key the microphone, so you *could* use i

#duo-art #ft-817

Okay, that conflicts with ELAD's wiring config, but I suspect you are right and I will order a suitable connector. Many thanks for your help (I'll contact you if the rig or amp explodes) :-))))) Regar

#duo-art #ft-817

Hello Thomas, you can't use the ACC Port and the CT-62 for the PTT Line. It does not exist at the ACC Port. Look in the 817 Manual Page 7 at the Data Port Schematic. There is a Pin named PTT. That's t

#duo-art #ft-817

I apologise if I've come across as a "shouter" but I am genuinely frustrated by the situation. I'm a Foundation Licence holder and freely admit to knowing bugger-all about schematics and electronics.
