High speed (38400 baud) TNC
I gained many information for a high speed (38400 baud) TNC from
SYMEK Co.. I express gratitude for Mr.Ulf Kumm, DK9SJ kindness.

There is moreover another TNC maker as follows.

Hello, this is JE9PEL / Mineo Wakita.
I would like to decord UO-36 and TiungSat 38k4 signals.
Is this able to use your SYMEK TNC31S and TRX4S ?
Please tell me how much US$ and how to order.
Thank you.

dr OM Mineo,
funny but the e-mail didn't work.
I tried several times with the same negative result.
Maybe it is just an temporary problem.
I send this e-mail to both addresses,
let's see which of them will work.
The mail to the jamsat.or.jp returned with the message:

Yes.
I am not absolutely sure about the modes of these sats
but the TRX4S is able to transmit and receive from
430 to 440 MHz (other frequencies upon request).
Frequencies can be set in 12.5 kHz steps via RS232,
the bandwidth is 9600 / 19200 baud FSK in narrow mode and
38 / 76 / 153 kbaud in wide mode.
The uplink is (as far as I know) on 145 MHz, so you will
have to use a separate 2m transmitter (9600 baud) for this.
The TNC31S with the mixed-speed modem can transmit only
9600 baud and receive only 38400 baud FSK.
An alternative would be the TNC3S with one modem for
TX+RX 9600 and a second one for TX+RX 38400. This gives
you more flexibility to work the 9600 baud downlinks as
well.
With TNC31 and TNC3, you can change the modems later to
operate with 76 kbaud as well.
When I tried to receive UO36, I had no problems with a
TRX4S of the shelf on a 70cm groundplane without preamp.
For best results, a tracking yagi and low noise preamp
will be very usefull of cause.

Yes this works.
You will have to make a special cable with a 5 pin
connector (TNC31), one connector to TRX4S as receiver
and one for the TS790 as transmitter.
Well, if you just need to expand the TS790 for high
speed reception, you may just modify this transceiver
with our F-IFD module (~110 US$). See the internet for
'IFD receiver for TS790'. However, we would like it
more if you order the TRX4S instead of cause.
Or perhaps you take the cheaper IFD as RX and a TNC3S
instead of TNC31 to receive both speeds?

I would not sent cash, but money order to my banc or
post would be OK. However, VISA/Master would be
best I think. Any way is OK - as you like. We can
even send post packets cash on delivery.

1st Jan 2001, 00:00 in Germany, 08:00 in Japan.
I had modyfied already TS790 for 9600 baud, and I had worked
it everyday using TNC241(TASCO) for Uo22, Ko23, Ko25, To31 etc.
I am thinking of decording Uo36 signals such as 38k4 baud.
This diagram is as follows. I am thinking a transmitter is
TS790, and a receiver is TRX4S. Is this thought correct ?
Does TNC31S include G3RUH type modem ?

The modem has a 5 pin round DIN connector (2+4) for 'one' radio.
Pin1=modulator TS790; Pin2=Ground; Pin3=PTT TS790; Pin 4=Demod TRX4S.
Normally, the connector is not included, so pse add to your final
order 'pse send a 5 pin DIN connector free'.
The cable between 1, 2, 3 and 4 will be Y-shaped (with 3 connectors).

Yes. There exists a special mixed baud modem for TX 9600 and

If I modify IFD modelu for TS790, can I use Uo36 with only
TS790 and TNC31S (up:9600 baud 2m, down:38k4 baud 70cm)
without TRX4S ? And can I modify it easy ?
In this case,

U-S9U TNC31S TX9600bd RS38400bd 23 000 Yen = 201 US$

The total sum 48 332 Yen = 421 US$

After modifying it, can I use as now TS790 for 9600 baud
satellites such as Uo22, Ko23 using TNC241(for 9600 baud)
in addition to 38k4 baud Uo36 using TNC31S(for 38k4 baud) ?
I'm going to switch TNC241(TASCO Japan) or TNC31S(SYMEK).

YES exactly.
The IFD adds a high speed RX data output to TS790.
You find the modification instructions if you start at
http://symek.de and go to 'satellite radio' and 'IFD'.
It is not complicated to add the module in an existing
transceiver.

Yes. That's it.
If you use a TNC3S with two modems instead of the TNC31,
you are able to receive both speeds (9600 AND 38k) without
changeing anything (WISP accepts data from both modems and
the modified TS790 receives both speeds)

Yes, if you use the TNC31, you will have to swicht RS232 when
changeing from 38k to 9k6 downlink. With TNC3 as controller,
the TNC241 would become obsolete.

Nearly OK. You cannot connect the modulation input of TS790 to both
TNC at the same time. You will have to switch TX here.
But the modified TS790 will have two independent outputs for 9600
and 38400 which go to TNC241 and TNC31.

TNC241(TASCO Japan) have all mode such as FSK, PSK, JAS, RTTY,
AMTOR, CW, FAX between 300 baud and 19200 baud.
Here JAS mode means that uplink is FM Manchester Code mode and
downlink is PSK mode. It is setting automatically at JAS mode.
This JAS mode is use for satellite Fo29. Therefore I will use
this TNC241 switching with TNC31S.
I order to you as follows:
F-IFD TS790 module 12 666 Yen = 110 US$
U-S9U TNC31S TX9600bd RS38400bd 23 000 Yen = 201 US$
UPS express 3.5 kg (4 days typ) 12 666 Yen = 110 US$
- - - - - - - - - - - - - - - - - - - - - - - - - - -
The total sum 48 332 Yen = 421 US$
(changing exchange rates for few %)
(Today, DEM 810.34 = 44.657,66 Yen = 390 US$)
And please send a 5 pin DIN connector free.
Thank you for your many detailed mails for TNC31S etc.
May I put these your much useful advice on my Home Page ?
I'm sure that many Japanese hams will be of great use.
I will send you later a card number splitting upper eight
figures and lower eight figures in sixteen figures.
