In an email exchange with Mark at Palstar about another issue he mentioned that 1.04A is the new version being shipped with all amps now. He didn't know why it wasn't on the web site yet. This was

Just got new LA-1K,? boot screen is showing version 1.04A What is this all about?? Cannot find any info on Palstar site.? Anyone have this firmware version or info? 73, W3KIT

Love the amp…use it all the time on SSB but was wondering if I use it on FlDigi etc. what do I need to know ? Thanks W4OZ Dennis

Hi Dennis, No Mark didn't mention it but it is interesting especially because the amp doesn't use ALC for CW so this spike you mention from the radio makes sense. This could also explain why it only

Hi Jerry, I'm sure Mark has mentioned this to you, but are you sure the exciter isn't spiking it's drive power? The ALC circuits in many radios have enough delay in them that they'll spike on

My LA-1K is connected to an HF-AUTO tuner and an ICOM 7610. I have the data cable connected from the 7610 to the amplifier. When the amplifier is in "Direct Mode" (using the data cable for PTT and

Thanks for that, I am surprised too the cable isn't just available 73, Jerry WX1FLY ( http://www.qrz.com/db/wx1fly )

I made the band switch cable as well but never have the need to use it.? Auto RF was pretty quick for what I was using the linear for.? I even try out using just the PTT cable on some Digital mode,

Thanks I tried that and destroyed 2 DIN connectors in the process trying to solder wires onto those tiny pins. I was hoping there was one already made like for my ICOM radios. I found one on eBay

Jerry, I have the same setup. You just need a PTT cable from 991A to LA-1K.? I am using 8 pins DIN plug and RCA plug in the other end. It will be pin 2 TX GND and pin 3 GND.? More in for can be

Does anyone here know what cable is needed to connect the LA-1K to the Yaesu 991A?

If anyone in the group knows of someone looking for a like new pristine LA-1K. Let me know off the reflector and I will put you in touch. Neil n4fn "at" arrl.net

If you get on CW you MUST have delay. Try it at low power int a dummy load and you should see what happens. If you have chatter you need delay. 73 Happy to help anytime Neil

Neil, thank you for your help and all of the trouble looking for the 991A set up. Yes, that is all pretty much I can see on my 991A manual. I guess I don't have to worry about it so much.? I only

I downloaded the manual for the FT- 991A, and it talks about the delay on pages 78 and 79. Further explanation of *hang time* is on page 85 under the heading of ""CW Time Delay Setting". I hope that

Komkit, This is from the Ftdx5000 manual I suspect you have something similar in the 991 manual. I will see if I can find it. 73 es gud dx Neil N4FN [image: image.png] [email protected]>

Komkit, As far as the discussions I have had with Paul at Palstar (Paul and Eva have been dear friends for many years, sadly I will miss having dinner with them at Dayton because at 85 the trip has

The LA-1K is NOT a QSK amp, so when running CW you must enable some hang time delay other wise the relay will be damaged. On my FTdx5000 this is enabled with the vox delay. This does mean you are

I think somewhere on this forum Paul, the creator of the amp, said that the vacuum relay in the amp will not switch until it senses RF. So no TX delay is required.? N1UB

Neil, The call here is W3KIT, sorry about not posting it down. Thank you for the reply. At any rate, very good to hear that I don’t actually need the ALC cable.??I am not an avid CW operator, I
