Thinking of a 30 meter vertical and also using it on 20 meters, which
is close to 3/8L. Like to know the approx. SWR of a 3/8L 20 meter
vertical, generally speaking, know some variances.

Thanks,

Will amateur radios still be able to listen to the narrow bands?

Will it affect anything?

  Thanks,

From what I can gather a software mod was done
by kenwood, but contrary to reports saying it corrected
the problem, knowledgeable people who say they have
tested it, say it just reduced it some, and it still is at
too high a level.

I don't know, would like to know if a high level really
is such a problem for an amp.

Seems like if this was such a problem amps would be going
out all over the place, doesn't seem so.

I'm interested in the effect on the new Elecraft solid state
amp, KPA500.

I just left the ARRL site, you can't download it, saw it was
Phil Salas AD5X, it rang a bell.

 Thank you very much.

OK, is the "two db attenuator" something you can buy ready made
somewhere?

Can you tell me what month of QST was the article in?

 Thank You,

Thanks.
 
There are several people no longer using the TS-590, such as some
on the Yahoo TS-590 Group, because of concerns for their amps.
Some have stories to tell about the danger.

I was about to get  a TS-590, started looking at the IC-7410, joined
their Group, and they just discovered the IC-7410 is spiking more
than the TS-590 on SSB, they have contacted Icom.

I was wondering if the ARB-704 would buffer it, guess not, oh well.

"Hopefully W8JI will come in and give his input ..."   I agree, I'd like to
know if it really is a danger to the amp.

    Thanks

I keep hearing about transmitter spikes(TS-590, IC-7410,etc.) and the
danger to an amp, if you use one.

The Amplifer-to-Transceiver Interface  ARB-704 is for spikes from
the amp to the radio.

QUESTION: Will it also buffer, prevent, spikes from the radio to the amp???

   Thanks,

The ones I've seen the RED RCA goes to the linear,
the other to ALC. But check.

If you have the 10 pin the ALC is in it.

You say you have the 10 pin, with it the ALC is
connected. You should have 2 RCA plugs on the
other end, one for the linear and one for ALC.

Thanks everyone.

I'm going to save W8JI's for reference.

15  eHam Forums / Amplifiers / Safety Question ALS-600 & solid state amps on: December 27, 2009, 01:38:43 PM
Is it correct that a solid state amp like the ALS-600
is safer to work on because once you have it
unplugged for awhile you don't have to worry about
massive capacitor build up of voltage that can
kill you.

Do you have to chickenstick everything?Huh

  Thanks,

     Dan
