[Repeater-Builder] TNC Carrier Detect, DCD

[Steve S. Bosshard (NU5D)]

Best I recall there was a choice between hardwiring COR to the TNC or 
using internal Data Carrier Detect for the TNC to recognize activity on 
the radio channel.  This was an input signal from the radio to the TNC.  
Way back whenSteve NU5D

That's what I remember also... my KPC-9612 is so old, I have no idea

Perhaps this was dropped in the newer KPC-3 command set, but my old
KPC-2 version 5.0 has this to say about the CD command:

CD INTERNAL | EXTERNAL | SOFTWARE   v3.0

...

When set to EXTERNAL, the carrier detect is supplied by an external
device, connected to the XCD pin on the radio port.

[Repeater-Builder] 2 TNC's into 1 Radio

Is this what you're looking for?

http://www.ccdx.org/zedyx/mods/2TNCs1Radio.htm

Re: Re: [Repeater-Builder] Connecting Multiple TNCs

[Ron Wright]

Nate,

I looked in my KPC-3+ manual and they do call out a DCD line on both the RS232 
DB25 connector, pin 8, and also on the 9 pin radio connector.  However, I 
cannot find any reference to it in the manual.  Probably there, but cannot 
find.  Wonder why they could put in a simple chart saying "pin 1, does this, lo 
or high to turn on/off".

In the RS232 spec the pin 8, known as CD, is Receive Line Signal Detector.  It 
does take the unit on/off line.

So I am assuming if the CD (DCD here) is in off state then the TNC will not do 
anything including receive or transmit???

Generally you have to put the Kenwood radios in to programming mode, then
you can read/write to it.

Try one of the following to get it into programming mode.

Press and hold the button below PTT and C button and then turn on. Wait a

>Whats wrong with a Dynamotor?

Well lets see, hi, just for fun.

1. very inefficent with it producing lots of heat.
2. very very expensive to make, component and labor wise (the labor factor goes 
away if made in China, but can't count on getting one that want kill you with 
normal use).
3. very heavy (minor factor in aircraft that requires 11 lb of air plane to fly 
1 lb of payload...on the Space Suttle cost $10,000/lb to fly).
4. very noisey, but so are the operators.
5. takes time to come up and deliever power.
6. not very well regulated, but for tubes not a problem.
7. takes up lots of space (in the progline took 1/3 of the radio.


What is good about a Dynamotor?

1. makes pretty good boat anchor, however, some of the materials are not 
friendly to the enviorment.
2.. all I can think of

However, some of the high powered first transmitters were Dynamotors.  Actually 
took DC motors, geared them up to the RPM and added poles to a generator so one 
got the kHz of frequency wanted.  Guess modulated the stator to get coil 
modulated AM.  Now doing FM...minor problem.  Did work better than the spark 
gap, but much harder to make and use.

Last place where I had a real job we had to have 400 Hz power (was military 
electronics).  A dynamotor config was used...60 Hz syncronise? motor coupled to 
shaft of 400 Hz generator.  Worked great.

The Dynamotor was what was avialable for the time, did its job and gave many 
like Vincent N6OA/2 and many others the pleasure of radio.

I love this stuff.

Whats wrong with a Dynamotor?  Ran my Moto 140-D just fine.  My

That's not what I recommended.  I recommended tying one's PTT signal  
to the other's RECEIVE signal so it would hold off and not transmit.   
(TNC's won't transmit over an incoming received signal.)

As someone else and myself both pointed out, you have to rely on  
having a real COS signal from the radio and have your TNC's set up to  
use that, and not use a "software" DCD (data carrier detect) that  
looks for real tones, you have to do it the "old fashioned" way with  
a hardware COS line from the rig.

> Unless there is some sort of feedback to tell a TNC to wait then

No, TNC's "buffer" data all the time.  If the channel is busy when  
the computer connected to them sends data to them, they buffer and  
wait.  Then when the channel's clear, they transmit that data.  So  
it's not really a separate "WAIT" line, you're just tricking TNC #2  
to think that the channel is busy when TNC #1 is really transmitting,  
and vice-versa.

This is kinda off-topic for RB, so I'll stop now -- but suffice it to  
say, hooking two TNC's to the same rig would be pretty simple... as  
long as you're not relying on the TNC to determine if the channel is  
busy, and you're using the "old-fashioned" system that simply watched  
the squelch circuit of the receiver... if the squelch was open, the  
TNC knew it shouldn't transmit.

(Once upon a time, there were endless debates about the benefits of  
doing busy-channel detection by either method, and which one was  
"better" over the last couple of decades... real "squelch" circuits  
will also give way to voice traffic on the same frequency... software  
DCD's won't... etc. etc. etc.)

No, that's just a null-modem cable between two TNC's to make a cross-

supposed to be the topic of this mailing list, but it's not what the
