Subject: [RTTY] TS 590s on RTTY
Message-ID: <ad46753d-1400-a93d-1124-4d970d82ab5e@verizon.net>

I am planning to help a local ham get his TS 590S on digital. I haven't
seen the rig yet, but have looked at the manual on line, which seems
Kenwoodishly lacking the needed details. My questions:
Can the rig run RTTY with only a usp-usp cable between the rig and
computer, which the manual hints at?
Is TS 590 FSK true FSK or is it internally generated AFSK?
If AFSK is desired, must it be run through the 13pin din connection?
Are all filters available in all modes?
I prefer not using interfaces, other than small transformer-isolation
boards and ptt connection.
Thanks for any advice. I have been spoiled by my K3.
73, Dave, K2YG

The Dayton Hamvention is rapidly approaching and there is still room left in
the informal RTTY Contest Dinner. Here are the details ...
When: Thursday, 18 May, 6pm
Where: Spaghetti Warehouse, 36 West 5th Street (two blocks from Crowne Plaza
hotel and three blocks from Convention Center parking garage)
What: Informal dinner with RTTY contesting friends (or, whomever)
Menu: choice of:
- Spaghetti & Meatballs
- Incredible 15-Layer Lasagne
- Fettuccini Alfredo
- Four-Cheese Manicotti
- Grilled Chicken Caesar Salad
Includes crisp fresh garden salad, freshly baked sourdough bread
and your choice of soft drink or tea
Cost: $21
RSVP: Ed W0YK with check or feeless (to me) PayPal transaction to
w0yk@msn.com. Mailing address: POB 1877, Los Gatos, CA 95031-1877
(Feeless PayPal transactions are done by choosing "Friends and Family" and
using funds already in your PayPal account or cash drawn from your bank
account. Any transaction type that uses credit cards will need to be for
$24 to cover the fee I will be charged. I can also process credit cards
directly for $24.)
A banquet room is reserved that comfortably holds 55 people, so the first 54
to RSVP with payment will get a seat.
"Program": Hank W6SX will moderate a round of introductions with each of us
sharing a favorite RTTY operating tip (hint, hint). Stu K6TU will give us
an update on the Makrothen RTTY Contest. Dennis W1UE will share how he sets
up and operates SO2R.
Raffle: If someone would like to put together a prize raffle, that's fine,
too. I can provide vendor contacts that Fred WW4LL and I used a few years
ago. Contact me if you'd like to help out.
Audio-Visual request: If you have a PC projector and screen you can get to
the dinner that would be nice for a couple of the presenters.
Hope to see you in Dayton!
73,
Ed W0YK

Hi Dave, I own a TS-590s and operate RTTY and digital modes.
>Can the rig run RTTY with only a usp-usp cable...
Yes, the USB port provides rig control (serial port) and an audio device. You
can
run AFSK or other audio digital modes without any more interface.
>Is TS 590 FSK true FSK...
For FSK you must use the 13-pin connector and send a shift signal. Works fine,
I
don't know what it might be doing inside the radio. I've never had a problem.
> If AFSK is desired, must it be run through the 13pin din connection?
AFSK can be through the USB audio device, or through the 13 pin connector.
FSK is through the 13 pin connector.
>Are all filters available in all modes?
No, FSK or DATA modes have a smaller selection of available filter widths,
compared
say to CW. And some noise reduction and other features are different or not
available.
But, I've never found it to be a big problem or overly limited my operating.

Greetings Diddlers:
Quite the active group last week with high scores all around. Even WD0T was
back from basement rehab work! The weekend BARTG 75 baud Sprint was a bit thin
out west here but I see a few Midwest/east coast guys worked a few. Looks like
the upcoming weekend has a Digital test on 10 meters (not going to hold my
breath on that one), so this Thursday may be your only shot at a little RTTY
activity.
So fire up the radios and join us for some keyboarding Qs.
Here are the details for our Thursday evening ditty:
Friday, 28 Apr 2017, 0145Z - 0215Z (Thursday, 27 Apr 2017 in NA)
-- 1845 - 1915 PDT (no reminders, everyone is DST acclimated)
-- 2145 - 2215 EDT
-- (others in-between those two)
-- 160: 1805 and up (Last two minutes seem to be popular?)
-- 80/40/20/15 +80kHz up from the band edge (check 20 at the start just in
case)
-- Same band dupes ok after 1 intervening Q.
-- 1 kHz QSY rule, otherwise standard Sprint rules
-- Mults per band
-- 100W power limit
Please visit http://www.ncccsprint.com/rttyns.html for complete rules and links
to other info. If you find any problems with the web pages, please let me know
so we can get them fixed.
If you would like to receive all the latest info about NS as well as a have a
place for comments and questions, sign up for the NS mailing list:
http://www.kkn.net/mailman/listinfo/nccc-blue
Report scores to 3830scores.com, and join us at 0300Z on 3610 kHz (+/- a few
for ongoing groups) for comments and questions (and dinner menus).
Diddle diddle,
Ken K6MR

Subject: [RTTY] MMTTY Tx Tab settings
Message-ID: <2544d1.4e86bdb0.4631f3e5@aol.com>
Content-Type: text/plain; charset="US-ASCII"
I'd like some info on setting parameters in the TxBPF/TxLPF box in the
MMTTY TX Tab section .
I can't find good documentation in the MMTTY help file. There has been
some discussion here recently.
The parameters and their apparent default settings (from most Profiles)
are:
Tx BPF check box [default = Selected?]
Tap (range 24-512) [default = 48]
Tx LPF check box [default = not Selected]
Freq in hz (range 40-600) [default = 100]
What do each of these do and what are the optimum settings?
Thanks & 73,
Ken, AB1J

AND *check* TxBPF (TX tab) it is not checked by default.
TxBPF is not needed for FSK and increases the processor
load (for marginal systems) on AFSK.
You will also want to set Freq (bandwidth) to 600 Hz (or
enter 400 Hz manually). 300 Hz is too narrow with 512
taps.

> Tx BPF check box [default = Selected?]
Enables a bandpass filter in the AFSK output. The bandpass filter
removes distortion products and harmonics.
> Tx LPF check box [default = not Selected]
Enables a lowpass filter in the AFSK output. The lowpass filter
removes harmonics, it does not impact distortion or switching
transients.
Note: these filters only act on the audio generated by the sound
card. They do not remove distortion/harmonics generated by
running the sound card at maximum output level (clipping in the
analog output) or over driving the input of the transceiver. Nor
do they remove hum caused by improper grounding/bonding of the
computer soundcard, interface, and transceiver.
> Tap (range 24-512) [default = 48]
Controls the steepness of the filter skirts. Full details is an
in depth topic on the mathematics of digital signal processing.
> Freq in hz (range 40-600) [default = 100]
Controls the width of the bandpass filter. Note: with high tap
numbers (steep sided filters) the bandwidth should be *greater than*
400Hz to prevent loss of "sharpness" in the mark/space transitions.
