Re: [Elecraft] K3 for CW

2012-07-06 Thread Robby.VY2SS
Hmmm.  To me a 1000 filter is a waste of a slot. Make it 1.8 and it is a big
help in the occasional SSB contest.
 
I wonder if I need the 400 hz in my sub. I only use the sub in a split
operation and like to set my DSP up to 600-800 so I can hear more of the
pile in my right ear.

Re: [Elecraft] K3 for CW

2012-07-04 Thread Robby.VY2SS
I had the same dilemma. I went for the 250 and 500 for the reason you 
mentioned. I normally listen at 350 hz but 250 in contests.
 
If you are mostly interested in CW why bother with the DVR?
 
The 2nd RX is very nice but I find that I seldom use it after the first few 
months.
 
I don’t think you need to match them. I have a 400 hz filter in my sub RX and 
have had good success with diversity etc. 
 
Just my 2 cents worth.

Subject: K3 for CW
 

I'm about to place order for k3 kit.  I'm currently only interested in CW, have 
a K2 I built, and want to spring for a K3. 
Currently my order includes the KAT3, KDVR3, 400  250 8-pole filters. 

I've been following P3, 2nd Rcvr here but am not ready for those yet.  My 
question is 1) best filters for CW and 2) any other must-have options. 

I've read Wayne's article about filter selection but still unsure.  It seems 
the 400 and 250 may be close to same and 1000 and 400 a better choice.  Or 500 
5-pole?  I'll be adding Sec Rx so what about filter matching?

Re: [Elecraft] Rev 4.51 firmware - what AGC settings worked on big pile-ups with loud AND weak signals in the WPX?

2012-05-29 Thread Robby.VY2SS
I had limited time available for the WPX and operated as VF2A. I loaded v4.51
beta before the contest to try it out. I tried the settings mentioned above
before the contest. I cannot imagine using them. I cannot imagine spending
the entire contest with my hand on the  gain controls to prevent serious ear
damage. I run my RF gain wide open. Always. I finally changed my settings to
the defaults in my owners manual. I contested with both hands on the
keyboard. I worked the weak stations with no difficulty and the strong ones
with no pain. I do not expect every improvement to be useful to me. Everyone
configures and uses their K3 differently. I am very impressed that Elecraft
is able (and willing) to keep improving our equipment. I have never
regretted buying anything from them.

Re: [Elecraft] RCS-12 or Station Master for K3?

2012-05-21 Thread Robby.VY2SS
I have been using the Elecraft KRC2 for remote switching for several years. 

It drives a MicroHAM 10 port switch. The switch is well made in a heavy
casting and can be used in the shack or on your tower. I have never had the
slightest problem with it. 

I built the KRC2 as a kit (easy) and the only problem came after a minor
lightning event which prevented me from communicating with the KRC2
proccessor to upgrade the S/W. Elecraft responded immediately with a new
chip with the latest software already installed. The cable interface with
the switch box allows one or more bands to use a single antenna.

I am an avid contester and it is great to have one less thing to remember on
a band change.

[Elecraft] No SubRX on 30M

2012-05-06 Thread Robby.VY2SS
I don't believe I ever tried to run split on 30M before so I don't know if it
was always this way or not.
When I called the 7O on 30M I was suprised that I could not hear the pile up
on the subRX. I can hear background noise in my right ear but when I see a
signal on the P3 and tune the subRX to it I hear no signal. Hear it fine on
the main RX. All other bands I use it works as it should. Checked the docs
cannot see where it might be disabled.

[Elecraft] Noise from compressor

2012-04-30 Thread Robby.VY2SS
Riddle me this!

I have strong interferance since installing an air source heat pump. It is
most annoying on 20M. It is also present on 40M and 15M. My 40M antenna is
twice as far from the compressor and the noise on that band  is reduced.  On
20M is is S3-4. It used to be S1. Here is what I have done in trying to
eliminate this problem:

1. I removed the 220VAC from the compressor at the breaker panel. The noise
is gone.

2. I turned the breaker back on and put my indoor units on fan only. The
noise is gone. I guess this proves the noise is coming from the compressor.
Also when I turn my beam toward the compressor the noise increases.

3. I disconnected my power supply and connected the K3 to a battery. The
noise is gone so It is not coming in on the house AC circuit.

4. I disonnected the antenna at the K3. The noise is gone so it seems it was
coming from the antenna.

5. I reconnect the antenna and turn the RF gain to zero. The noise is gone
from the speaker but on the waterfall it is NOT gone.

I am hearing a buzz in the speaker or headphones and can see many vertical
lines on the P3 waterfall. The wider my bandwidth setting the more noticable
problem but the lines are there for the entire width of the P3 scan. Maybe
40 lines on P3 display with a 5 khz scan width.

I have tried placing 3 capacitors across the 220VAC terminals where it
connects to the compressor. LG, LN, NG with no measureable results.

I would be very happy if someone can shed a little light on this.

73,

-Robby
VY2SS


So the noise is present in the IF

Re: [Elecraft] K3 - Choice of filters in KRX3

2011-10-27 Thread Robby.VY2SS
Stewart,

I operate mostly in the CW mode and some RTTY. In my second RX I have a 400
hz 8 pole. My main RX has 8 pole 500hz and 250 hz filters not counting the
SSB ones. I normaly listen with my width set at 350 and down to  200-250 in
a contest. I can see no reason to have the same filters in both recievers
even using diversity.
I have never tried SO2V operating but I would be interested in hearing more
about it since I seem to have the hardware for it.
If you sell it, buy a P3 with the money.

Don't look at the P3 when you are fast tuning the K3.

Re: [Elecraft] Spot button QSYs K3

2011-10-21 Thread Robby.VY2SS
I spent some more time with this and find that if I tune to the low side
(tone lower than my pitch setting) and push spot it tunes the way it should
but if I turn the dial to hear a higher note than my 680 hz pitch setting
the VFO takes off down the band. It will sail right past S9 signals without
stopping.

I have 250 and 500 hz filters installed (both 8 pole) and my DSP width set
at 350 where I normally have it. 
I am using version 4.39 as previously mentioned. 
My sub RX is off. 
I don't like turning the P3 off because it's like going blind but doing so
has no effect on the problem.
Pressing TEXT DEC I have AUTO OFF and Threshold set to 1. Setting it to a
higher value does not give me a relialbe tuning bar.
VFO CRS is set to 0.1
VFO CTS is set to 400
VFO FST is set to 50
VFO IND is set to NO
VFO OFS is set to ON
Pitch is set to 680 but other settings have produced similar results.
I don't always use SPOT as the P3 allows me to tune just as accurately and I
am usually already looking at it. 
I did not notice this SPOT problem before my last F/W upgrade although it

[Elecraft] Spot button QSYs K3

2011-10-19 Thread Robby.VY2SS
Using F/W upgrade 4.39.

I just noticed that when I push the spot button the K3 will QSY down a
little over 2 khz. It is never the exact same amount. It does not
necessarily stop on a signal. This happens when I have a CW signal in the
passband or not. The last three times I did the calculation it went -2.176
khz, -2.146 khz and -2.189 khz. Is this a result of my recent upgrade or
finger trouble. (again)

Re: [Elecraft] Proper K3 filter/options selection?

2011-08-26 Thread Robby.VY2SS
Paul,
I would suggest getting an 8 pole 500 hz filter instead of the 400 hz one.
You can order it from INRAD for the same price. It gives you a little more
spread between the two filters.

Re: [Elecraft] need some roofing filter advice?

2011-07-18 Thread Robby.VY2SS
Hi Chuck,

I was faced with the same questions last winter when I added the second RX. 

There was some concern that diversity reception would suffer if the two
recievers were not filtered exactly the same. Since I considered diversity
reception to be a bit of a gimmick I went with just two filters. The 2.7
5-pole that is included and an 8-pole 400hz filter. My main RX has 2.7, 1.8,
500 and 250 filters, all 8 pole except the 2.7.

A few months later I discovered that I had been wrong about diversity
reception. It is actually amazing and it works great with my filter
combination. 

If you are working CW DX, you will be listening on the subRX and I find it
useful to open the subRX up as much as 600 or 700 hz on some pileups so I
hear more in the right ear and the narrow filter on the DX in my left ear.
Team that up with the P3 and you are gonna be happy.

I got my 8-pole 500hz filter directly from INRad.

Re: [Elecraft] New to Me P3 Benefit

2011-03-06 Thread Robby.VY2SS
I have also found that my SP productivity has improved dramatically using
the P3 both on CW and RTTY. It's a big advantage when tuning up or down the
band to be able to see what is happening  ahead of you.  

On RTTY I will usually line up the marker on the next signal and jump to it
with the tap=QSY on the P3. I use the 5 kz span without the waterfall. With
a little practice, no manual fine tuning is necessary. I seldom have to
touch the main VFO on the K3 while I SP in that mode. I wish I could do
that with a mouse (hint). On CW the P3 together with the second RX allows me
to find and ID stations before I get to them.

It has always cost me points in contests because I am lazy and prefer to RUN
but now I'm getting much better rates from SP and that encourages me to do
it more.

When I'm looking for a RUN frequency, if there is one, the P3 helps me find
it.

My eyes are on the P3 almost all the time when I'm operating.

Re: [Elecraft] [k3] Audio distortion on strong CW signals - after a while

2011-01-29 Thread Robby.VY2SS

I noticed this for the first time in the 160M contest last night. It almost
sounds like aurora or a faulty relay at the transmit station. I switch to
the RX ant and everything was fine. I used my beverage a lot even to the USA
because of this. I found that when I had a chance to reboot the K3 the
problem was gone for a while. 

Could it be one of those COR gadgets reacting to the huge signals in the
contest.

Re: [Elecraft] KAT3 Automatic Antenna Tuner

2010-03-24 Thread Robby.VY2SS

Thanks for the fast reply Don.

Actually, I did expect it to automatically retune when it finds an SWR
higher than some specified amount. That is how every internal tuner I have
every used worked. Thats how my backup radio works and its a good thing I
have it as I have had quite a bit of down time waiting for new KAT3 boards.
Elecraft support is very good about sending them out but it takes 2 weeks to
get to me.

Unfortunately, although I suspected something was amiss, it was not until
recently that I discovered it was not really automatic (by my definition). I
agree that a normal person might have keyed in on it sooner.

Since 99% of my operating is in contests, I am not used to spending a lot of
time pondering various settings on my rig before each transmission. The more
set and forget the better I like it.

The problem with automatic selection of memorized settings is it stops being
useful when you change to an  antenna that has different charactaristics. Or
you turn on an amplifier that presents a different load than your antenna.
In these cases your memory settings are all working against you.

If I always used the same set of antennas and always did or did not use an
amplifier I would not be having these problems. At least now I know that to
be safe I need to press that button before every transmission after an
antenna or power level change. I have a hard time accepting that as
automatic but it may well depend on an individual's definition of the word.

I would prefer to have my tuner ensure that my finals are not seeing a high
SWR. 

(K4... and K8.. please do not flame me. You know who you are.)

Re: [Elecraft] KAT3 Automatic Antenna Tuner

2010-03-24 Thread Robby.VY2SS

Don,

That sounds like a useful suggestion.  At least it did unitil I thought
about it a while. 

Connecting the input of the amp to port 2 is easy but what do I do with the
output. Antenna port 1 is already connected to my antenna switchs. What do I
do with the output from the amp? I could maybe connect both ports 1 and 2 to
the amp input and the amp output to  the switch since only one at a time is
active but what happens when the port in use is sending 100W back into the
unused port? That scares me a little.

Elecraft support have kindly sent me a KANT board so the other solution
would be a third party 1KW external tuner. I am not in love with this idea.

Re: [Elecraft] KAT3 Automatic Antenna Tuner

2010-03-24 Thread Robby.VY2SS

Hi Monty,

That sounds like a lot to remember but you obviously can.  I also have my 6M
antenna on port 2 also but it does not have to be that way. I can monitor 6M
with anther rig.

I have purchased and assembled the Elecraft KRC2 band decoder and use it
with a 10 port remote switch. The switch is not all that remote. It'is here
in the shack but it is a great setup because I never have to worry about
transmitting into the wrong antenna. Most radio manufacturers provide band
data on the back of the rig in some form or other so this can be
accomplished. For me it is a huge benefit. As a matter of fact it works so
well I stopped thinking about antennas a whole lot during a contest. Most of
my antennas do not require a tuner in the CW part of the band where I
usually reside but I use it anyway just so I don't have to worry about what
part of the band I am in. This all good as long as I stay on low power and
don't manually switch in a special antenna such as NVIS or a loop.

I have to think about putting the NVIS antenna on port 2. I need to be able
to transmit on this antenna on more than one band. That will solve a portion
of my problem.

the MFJ-4726 to select between barefoot or amplifier inputs, and direct the 
output to one of three antennas or a dummy load.
