Ideally I can run two Panadapters, one for each RX. In the real world I
expect I would only use one with it connected to the sub RX.

Ian,
Check the voltage, current and polarity of the 811 amplifier PTT
signal and compare those to the rating for the KPA100 maximum
ratings. If the 811 amp requirements fall within the ratings of the
KPA100 amp keying output, then just connect them together and run.
OK,
But in two years there might be something new!

Ian, yes it is as simple as that. Phono to phono cable.
Look at page 65 of the KPA100 manual, centre left, you will see J7 and
the switching transistor. The main thing is that the amp shouldn't
exceed the device's parameters, page 59. 200V DC and 1 amp.

Hi Ken
I have one that might be what you are looking for.
I use it with TR LOG here.
The mfr is BTC, and I think the model is 5100-C.
It has no numeric key pad. It has 10 F keys.
Width is 11.75 inches by 6 inches deep.
Really fits well on my small operating desk.
It has foldup legs at the rear to
Will the K3 Keyer have Auto Character Spacing?
I don't like the K2 Keyer as it doesn't have ACS so I use an outboard

would mean I needn't take a separate Keyer on /P operations when I get
my K3, which is now on order!!
If someone already suggested this one, sorry.

Hi John. This is already a done deal...though I'm not
sure what the final outcome was. This was for T-Shirts to
bring to Dayton and the team is already on their way.
Thanks for the suggestions...was fun reading everyones

Brett,
There ARE kilowatt baluns, but the balun probably will not help a G5RV due
to the fact it is resonant on 20 as a gain antenna, and somewhat of a
mismatch on any other band. In fact, you would be better off running open
wire line all the way to a Tee tuner, then using a ferrite bead 1:1

The 756pro has no roofing filters, yet there is little
or no AGC pumping when listening to an S2 signal with
the DSP filter set to 500hz and a S9 signal is within
the 15khz first hardware filter. I'm hoping the K3 can
do at least this well without switching in a roofing
filter of less than 2.7khz.
Don,
I don't think the concern here is with S9 signals, but
rather much stronger ones. Here is a clip from Erics
article talking about roofing filters..
If you only use the 2.7 kHz stock filter for CW or data
operation you will be significantly desensed once signals

Readers would do well to actually read the posts or do a SEARCH on the
archive.
Will you have an issue with only the stock roofing filter? Eric
already gave us the answer with parameters.

Right, Greg. We're talking about VERY strong signals here.
For example: This is why dynamic range is so important to 6m contesters.
Signals on 6m during intense sporadic-E (Es) openings can be incredibly
strong, due both to the shorter ionospheric path for this kind of propagation
and to the

K5KVH sums it up in his opening paragraph ...
I have G5RV's original article introducing the antenna.
He specifically states that it is a 20M antenna, and yet it's

cult thing. The same thing happened with the single-wire fed

Right. I wrote, ...this 0.5 uV S1 signal... Actually, at 5 dB per S-unit
and S0 = MDS (0.25 uV), S1 would be about 0.44 uV... But hey, that's
reasonably close to 0.5.
Hi Bill,
How many dB an S-unit is depends on where you start from to get there.
Nope. At least on our side of the puddle IARU Region 1 Technical
Recommendation R.1 defines how many dB a S-unit is.
One S-Unit *is* 6dB.
If the K3 is not 6dB per S-Unit, then yet again another useless S-meter
Toby,
Interesting. OK, I wasn't aware of that. Over here, it's a source of endless
debate (a bit of which I was engaging in). I'm quite certain there are no US
standards for an S-unit (IEEE, ANSI, etc.) Could be wrong, but I've never
heard anybody claim such.
I guess we give Wayne et al. a
In my 56 years of hamming I've always thought the standard was/is
