I understand that, I know several friends that enjoy JT modes, I used it a
lot on Meteor Scatter and few QSO's on EME, Actually I gave up on EME
because I like CW and really few JT modes boring, it is personal.

My point is, and what I stand for,  do not give up on noise!

I proved you can reduce the noise flor with horizontal phased loops. Not
only here but on 30+ places, and  in different countries as well.

You and my friends enjoy JT modes, I respect that and wish all the best . My
old brother by choice, PY1RO is very active today on HF just because JT
modes. 

It is a personal decision.

My choice was to fight noise, stay put here in my city lot, help others to
do the same, I am not special at all, a very poor CW operator. I don't
contest too. 

JT modes is not a solution for noise, it is just easy.

I have JT installed in my machine, I can tell you if the guy is -22db on the
vertical TX antenna,  the same signal is +1db on my HWF. I can hear hundreds
of station on any given night on 160m using my HWF on digital modes. Zone
23, 24, 26 and 28 are active on 160m, WSJT, hundreds of YB stations are
active on 80m, digital mode.

I just don't like JT modes.

Amateur radio is about communicating, regardless of the mode.

Chokes don't solve an RF noise floor issue if the RF noise is generated by
devices you don't own or control.

For my station, and I have space for it, everything is choked, and I mean
everything.  I bought cases of chokes.  Yes, they helped all I could
control.

The other thing is that the bulk of the 160M dx on a given night might just
be on a digital mode.  There have been nights I could only hear 1 or 2 CW
signals, and they were in North America.  Yet, on JT65 there might be 10 new
countries show up over the period of an hour or so.  It is actually pretty
impressive.

Regardless of the mode, they are still valid contacts.   No one said that
everyone had to do it.  It is about options, and there are many.

I am also suck at CW.  Yes, I have done it for 45 years or so.  I can do
it, but I don't enjoy it.I have have some CQ WPX CW contest paper to
prove it.  LOL

Amateur radio is many things to many people.  No one said you have to comply

If you convince him to upload to LOTW, you will have the qso confirmed

of 08:30 utc I filled the qsl with 20:30 utc

The JA card checker rejected the QSL. That's very good!

Hi everyone,

Here's my stance on awards such as DXCC and achieving them with digimodes
such as JT65. Honestly, they're only worth the amount of importance you put
into them. They're essentially made up radio points anyway. If DXCC means
SSB and CW only, good for you. If you're having fun working working DXCC
with the JTmodes, good for you. If you only count entities worked from
stations you've built, good for you. If you operate from large stations that
aren't your own under your call, good for you. Honestly, that piece of paper
means something different to everyone. Isn't the whole point of this hobby
just to enjoy getting on the air, make new friends, and pray that the sun
doesn't obliterate the ionosphere?

Just my $.02.

Re: Topband: CNN notch filter recommendations

2017-05-14 Thread Richard (Rick) Karlquist

I've done a lot of filter design.  I am assuming that your requirement
is to remove a single station, and that you don't have any requirement
to pass the rest of the BCB band.  The question is: which is more
difficult:  a single frequency notch or a traditional high pass
filter that filters out the whole BCB.  To get 50 dB in a notch,
you will need to have multiple resonators in cascade.  You have to
watch the insertion loss since you are putting 100W through it.
So by the time you get done, it is not clear that the single
frequency notch is easier.

That's filter theory.  But in the real world, there are various
off the shelf high pass filters available, and even construction
articles if you want to build your own.  A 50 dB notch filter, OTOH,
will not be off the shelf or even have construction articles.
There might a software program somewhere to design it, but you
still need to know what you are doing.

A particular problem with notch filters is that many designs are
based on a notch within a bandpass.  IOW, you only need to
pass frequencies near the notch.  In your case, you need to
pass frequencies way above the notch.  Now you are even farther
off the beaten track.  This is probably only for the filter
enthusiast.

The commercially made filters have rejection that varies with
the frequency of the station.  You didn't say what the frequency
of the station is.  If it is fairly far down in the band, nearly
any filter than can handle the power should work.  If it is on
1690 (we have one of those here), you need the top of the line filter. 
Watch out of specsmanship games on the data sheets in that case.

Some filters may talk about rejection at 1500 kHz.

Yes - almost but:
You have to complete your QSO  on yourself
You are not obliged to use any PC or any other supports. If you do, then it
would not be a valid 100% QSO between two OPS.

That is my 10 USD worth

Hi everyone,

Here's my stance on awards such as DXCC and achieving them with digimodes
such as JT65. Honestly, they're only worth the amount of importance you put
into them. They're essentially made up radio points anyway. If DXCC means
SSB and CW only, good for you. If you're having fun working working DXCC
with the JTmodes, good for you. If you only count entities worked from
stations you've built, good for you. If you operate from large stations that
aren't your own under your call, good for you. Honestly, that piece of paper
means something different to everyone. Isn't the whole point of this hobby
just to enjoy getting on the air, make new friends, and pray that the sun
doesn't obliterate the ionosphere?

Just my $.02.

Hi all,Has anyone had "success" notching out a single AM bcb station that 
+50dB?I see a lot of bcb filters that are commercially made, but wanted some 
real world feedback from someone that has dealt with it.I'm looking for 
something that I can leave in-line between the rig and the amp - that will 
handle at least 200w.Any input would be appreciated.ThanksKevin KL7KY

Well stated JC!!
I fully agree.
The local QRM is getting worse each year with all those LED:s and other ,
mostly tiny things radiating several hundreds meters. Only two ways to go:1
Identify the QRM source and get rid of it, 2: Try to improve your RX
antennas.
To me, a 160 QSO is between 2 OPS sitting in front of their radios.

I kindly can't agree with that. Yes , noise is going up, but there are so
many things you can do to reduce the noise floor, chokes, small RX antennas

All of this requires some dedication and it is not easy. However far from
"not possible"

My city lot is noisy as everybody else, I works 135 (CW) countries for the
CQ Marathon since Jan 1st 2017 on 160m. My total on the last 10 years is #
291 confirmed on 160m, 39 zones.

My back yard is 100x150ft. not so small for a high performance station on
160m.

The digital mode is a choice, only a choice to avoid the hard work to enjoy
a DX on 160m. 

Digital mode  is boring as watch grass growing. But it is an option where
the PC try to do a connection with other PC using the antenna you have,
nothing wrong with that if you enjoy it.

It is not a solution for noise. It is a computer calculation that narrow the
BW to few Hertz or less than one Hz. 

The decoding is another thing. I personally don't consider a QSO, just a
machine to machine connection. 

The human operator is an option, all communication could  and can be done by
software as well. 


 Again it is just a personal thing.

Hello

of course we have choices and we can all do it any which way we choose.

My question was about the feeling of doing a CW and a JT65 QSo on topband.
I worked a new one on JT65 and really didn´t feel the excitement working it
as I did with any new one on CW

Maybe for digital lovers is great. They feel the same working RTTY or JT65?

Re: Topband: Top Band and JT65

2017-05-14 Thread Joel Harrison
Currently available DXCC awards are:
CW only DXCC
SSB only DXCC
Digital only DXCC

Then there is the "Mixed" DXCC award you can acquire that includes all modes.

So the segregation already exists if someone wants to take advantage of them.

A polite request to the reflector folks (unrelated to this specific post
from Mark) PLEASE identify yourself AND your CALLSIGN at the end of your
thread. Some folks just type their message and who they are in amateur
radio circles is not identified in their email address. Its a personal
thing. I just like to know who folks are. Thanks.

True enough, but time marches on.  This is similar to the discussion 
about whether Columbus or Captain Cook would have used GPS if it had 
been available, or instead navigated without it just for the challenge.  
I have, in fact "navigated" once across the Atlantic using a sextant, 
but I made use of time signals and a programmable pocket calculator.  I 
compared results to Satnav, the 1-satellite doppler predecessor to GPS.  
I guess this was the equivalent of using CW vs JT.

I've worked 20 new countries on 160m this winter alone on bands that are closed 
are so polluted with RF noise, that it would not be possible with the human 
ear. 

It also allows those that are space limited to get on and be rewarded with
