Re: ALC cable


Neil Foster
 

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 helps. As I mentioned earlier I do not know how other radios handle "hang time" and QSK issues. You have two fine pieces of equipment, enjoy them and take care of them.

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.

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 gotten to be? a bit much for me). OK the personal stuff aside.
The LA-1K is NOT a QSK amp so in CW one must insert delay between the dits and dahs otherwise the relay will damage itself in the radio. On the Yaesu FTdx5000 it is set when in the CW mode by advancing the VOX delay control. This does NOT mean you are using VOX in SSB. It will only have this effect in CW. That is how the 5K handles it. Check your 991 manual and it should address this, it should be the same. If you have any questions drop me a personal email and i will call you on your phone. Email me at n4fn "at" (replace the "at" with @ )

Neil? N4FN....BTW typically modern rigs do not use ALC feedback, but most older rigs did

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 do when I see some station I need or perhaps during some contests.? Otherwise pretty much SSB or some Digital mode.? For Digital mode I am not worry about it, maybe I went up to 100 watts only a few times. ?Beside, I do have another dedicated FT-991A for Digital mode that is not hook up to this linear.

Where do you set the TX delay on the FTDX-5000?? What does the menu call?? Maybe similar to 991A.

On SSB,? I am not using VOX just the good old PTT button on my MD-100 desk mic.? However I may be using the linear up to 250-300 watts next time I get on RTTY.

I could not really find any info about the TX delay much at all.? The document is saying very little.? I got the amp late Friday day, I call Palstar and left the voice mail.? I have not yet speak to any one,? I guess it was Friday and getting close to their cutting off time.

I do not know if the TX delay is apply to every mode this linear support or just CW, may be RTTY or Digital.

73, Komkit W3KIT
