Hi!
I have the question. How much better working KDSP2?
It has very expensive price. Are the KDSP2 really so good
working that I have to pay half K2 price?
TNX for any answer!

HI
I have the 3080 module fitted in my KX1 and I have already done the power
mod
With the display reading 13.5v I get the following outputs
All power outs measured using the elecraft DL1 and a good Calibrated Fluke
Meter
80m = 3.74W
40m = 4.14 W
30m = 4.74 W
20m = 3.12 W
Running
I am very serioulsy considering getting a XV-50 for 6m to replace my old
FT-620B rig (lots of good Q's from that one!) and have a question:
I know that the XV-50 ouput is 25w, but is there a way to _modify_ it so
that its max output is around 10w? I have a 10w -- 150w brick that I would
like
It depends on how you operate Alexander.My experience with the Ten-Tec
Orion's DSP as well as external audio DSP's on the K2 convinced me not to
buy the KDSP2 option for the K2.
I mainly operate CW. I tune around at 800Hz bandwidth but typically operate
at 150-200Hz. At such narrow
To me that's like saying The MFJ antenna analyzer has given me nothing
but trouble therefore I won't buy ANY antenna analyzer.
I won't go into what company I think is gradually buying Ten-Tec as
their founders die off.. Alex.

Actually it might be more like saying The MFJ antenna analyzer cannot be
used in strong RF fields and other analyzers that I have used cannot be used
in strong RF fields so I wouldn't recommend buying an antenna analyzer to
check a Field Day dipole attached to the tower of a 50KW broadcast

I have done 2 of these conversions and noticed something to be careful
of...Underneath L2, in back of J7, leads L2-1 and L2-4 pass over each other and
can short out toroid L2...I used a dental pick to move the wire lead from L2-1

Kenwood MC-43S hand held mic for sale, nice addition for the K2 since
the Heil MH-2 is now obsolete. Set the compression to level 3 and the mic
gain to 2 and you are in business. No more resistors on the mic header to
worry about. I want $45.00 plus 4.75 for Priority Mail shipping.

Sure! The output power is controlled using the POWER control on your K2, or
other 28 MHz if you're not using a K2. If you have a 28 MHz rig without

I have both of them. Keep in mind that I am only a CW operator, so you
will have to get the opinion of an SSB
Great reply Vic,
Let's widen the question to make it KAF2 or KDSP2 or NOTHING? Does the
basic K2's crystal filtering work well enough that you (any of you)
would be happy with no AF filtering or does the AF/DSP filtering add
enough that you wouldn't want to be without it?
- Keith KD1E -
I find the crystal filter more than adequate for my type of CW operation and
have felt no need to add any audio filtering.

Selectivity has
When I had narrow filtering in my Omni V I found that S/N did not
increase as bandwidth decreased. Instead, the noise began to sound like
signal since both were at the same frequency. Add some filter ringing
to the mix and sometimes the narrowest settings made copy worse.
As always, I reserve
Same here, Dave. I operate for fun. When signals are so bad I have to crank
in $300 filters, it's time to find someone stronger or QRT. I can't imagine
a QSO so important that I have to strain to hear it. I had a KAF2 and had a
chance to sell it to save for a KDSP2. I found I could still do what

One nice feature of the DSP for CW operation is the ability to open up
the filters for bands that seem to be dead or have little activity.
You set the crystal filter to its widest bandwidth and put the DSP in LP
(its widest setting). Activate the denoiser.
The band is quiet, background
Hi OM's YL's!
My favorite mode is CW. And I'm live in big industrial town (QRM).
Now I think that the rigt way for me - it's KAF2.
Hope with this option I will better selected a weak signals from QRM/QRN.
But internal K2 XTAL-filter is great!
Thanks for everyone for interesting discussion.
Keith - I do CW only and use the KAF2 and think that it is an improvement.
But not to decrease bandwith, the IF filters handle that chore very well. A
bandpass or lowpass AF filter cleans up internal noise that I find tiring.
Another solution maybe headphones that cut off high frequencies. I

I spent a few years with just the stock K2 when it came to audio
filtering. Thought it was great just like it was. Last year I put the
DSP filter in. Now I am sold on it. I love the noise removal function
on the thing. I find that if the noise
FWIW,
I operate CW only and have the KAF2 and the KDSP2 installed in my K2. For the
most part I find that I only need the XFIL set to FL2 at 500Hz. However there
are times when the bands are crowded or noisy and I am trying to work a weak
signal. Then I find that the KDSP2 with the Denoiser
I would strain to hear a P5!

Idiom Press make a SCAF-based audio filter called the SCAF-1. It's a
low-pass filter with a variable upper cutoff frequency. It also operates
in real-time with no ringing. Recordings of the SCAF-1 in action are

Hello all!
I'm very excited about this vertical as hiking season is here.
I'm still in the prove-in stage, but it looks very promising.
I have a vertical antenna system that should weigh-in around
7oz excluding the coax on 40m, 30m and 20m with SWRs
around 1.5 or so. Today I just added some 15m
Sir, you are my hero, since you are not just talking about designing
antennas, you are designing 'em.
Let me know your web site or something when this is ready for prime
time, I may well buy one!
