[GreenKeys] percentage of machines running vs use of electronics to view ...

Sat Jan 28 11:56:25 EST 2012

This is  good to know there is an auto cr/lf  for the 28...  probably not  
for the   15 though...

Now that I finally have a license I will have to figure a way to get on  
the  air... but...  want to try to  do it  with the old  iron!

Hi Ed, 

I have three Model 28 machines, two ASR and a KSR that I use almost daily  
on HF radio in the Amateur Radio Service.

The first ASR is geared at 45.45 baud for regular ham radio - this is my  
workhorse machine.

The second ASR is geared at 50 baud and came to me from Western  Union 
Telex service. I use this TTY to copy the weather traffic from the  northern 
German station, DDK9, at 10100.8 kHz.  This station is running a  450 Hz shift 
and is running in reverse with unshift on space disabled.   

The third Model 28 was originally obtained via NCARTS, an original  "mouse" 
machine from 1970.  This has been modified with a three speed  gearshift 
and is used for occasional 74.2 baud Amateur Radio  service. Yes, it does 
happen as there is a 100 WPM contest run by BARTG,  the British Teletype Group 
and very occasionally a DX RTTY contact.  My  last 100 WPM RTTY contact 
outside of a contest was back in the spring when I  was able to work Alain TR8CA 
in Gabon in west Africa on 10M. 

Just to let you know the number of Amateur Radio stations on the air,  I've 
worked 259 countries in total and over 100 countries on 10M, 12M,  15M, 
17M, 20M, 30M and 40M, all since 2004. Awards are still isued by a number  of 
the national RTTY organizations and you can see my list of RTTY awards at  
_http://www.qrz.com/db/WA3FRP_ (http://www.qrz.com/db/WA3FRP) 

At present, I am also using MMTTY for contests as it is difficult to  
handle the exchanges vai keyboard or paper tape over an entire contest  weekend. 
And, logging a couple of hundred contest contacts takes a lot of time  
post-contest.

I haven't had problem with characters piling up at the right hand  margin 
in my contacts with others using electronics since I've added  auto carriage 
return and line feed plus non-overline to each of my machines.  This is via 
standard mod kits for the Model 28s.

I have used a number of sources for paper in the past but not the  original 
yellow paper.  Most recently, I have been used recycled paper  which is 
off-white.  Looking around, you will find a number of  sources for white or 
off-white paper including:

_http://www.discountofficeitems.com/technology/office-machines-electronics/o
ffice-machine-accessories/calculator-register-rolls/perfection-teletype-roll
s/p22427.html_ 
(http://www.discountofficeitems.com/technology/office-machines-electronics/office-machine-accessories/calculator-register-rolls/perfectio
n-teletype-rolls/p22427.html)     $4.20 a roll for 36 rolls and occasional 
added discounts.  There is a  special this weekend.

_http://www.adorablesupply.com/items/~teletype-paper-rolls~/list.htm_ 
(http://www.adorablesupply.com/items/~teletype-paper-rolls~/list.htm)   where you 
can get twelve rolls for $51.08 ( $4.26 a roll)

and 

_http://www.bizrate.com/paper/teletype/_ 
(http://www.bizrate.com/paper/teletype/)   which gives a nice list of multiple sources on a single page

I wish that more hams were using teleprinters but even John GW4SKA in  
Wales has ditched his Creeds.   Oh well!

Just curious,,,

What is the  percentage of machines running vs use of electronics to view  
RTTY?

also... where can we  get cheap  yellow roll  paper for the history display 
here?

Many Thanks

Speaking strictly for myself, I only  use electromechanical TTY devices. I 
"listen" to an internet TTY source  called Heavy Metal that sends out AP 
headline 
newslets. Use an old  computer to "copy" the transmissions, and a Black Box 
RS-232 to Current  Loop unit to drive the TTYs. I am getting ready to start 
(hopefully sooner  than later) copying ITTY (which is an internet 
transmission of 
user  generated news that the receiving computer generates an AFSK signal 
to  
drive a TU with. Since I do not really like sandstate electronics, I am  
busy 
re-capping a TT/L-2 TU that has more tubes in it than carter had  pills. 
?
There is really very little true RADIO RTTY on anymore, and by  that I mean 
RTTY 
that has the carriage return signal at the end of every  line so that the 
machines will advance lines. Without that signal, the TTY  will type to the 
end 
of the line and then simply hammer away at the same  last position on that 
line, 
giving you a nice hole in the paper.  
?
There are several true RTTY signals out there, but I have not copied  any 
so far. 
Search the forum here and there is at least one weather  transmission and 
then 
there is a very dedicated soul who is running true  RTTY on the amateur 
bands (I 
cannot remember either source at the  moment).
?
Hope this helps!
?
Joe
