[Elecraft] SCS Pactor 3 modem with K3

[Johnny Siu]

Hello Dr.  Werner.

Thanks for your reply.  I will try to work on the set up of K3 + Modem + 
Airmail in my PC.  My purpose is to run Airmail in my notebook via K3 + SCS 
modem.

The link between my notebook PC to the SCS modem is via blue tooth (or USB).

Therefore, I am now working on the connection cables between K3 and the SCS 
modem.  Unlike the Icom / Yaesu / Kenwood, SCS do not make specific cables for 
K3.  I am going to build the connection cables myself.

BTW, I would take this chance to THANK all the replies either on the list or off 
the list to my questions on this topic.

SCS modem is expensive but by far the best one - Pactor 3.  I trust it has been 
widely used by marine and ERU of Red Cross.  I also send my question to SCS 
modem and reply is awaited.  The hams in this reflector respond to my questions 
very quick.


 cheers, 


Johnny VR2XMC

not true. There is no problem to control the K3 using the SCS Ptc-2.
Use the Kenwood protocol. "trx ty k 38400 A" for example will set your Ptc-
2 to 38.400 baud on VFO A and you can scan the frequency list without a
computer running.
The old Ptc-2 uses TTL levels, so you might need a level converter
(MAX232) and with the new Ptc-2pro or USB set the TRX TY to V24.
I have built a SCS Trx-ptc modem inside my K3 and K2.

In addition to this, Airmail after version 3.4 directly supports Elecraft
K2 and K3 transceivers. (also setting the correct mode) You can use either
a direct comport or the Ptc-2 trx control port. I think it was me who
persuaded Jim KE6RK into adding the Elecraft transceivers to the list of
supported radios in Oct. 2008 ;-)

I think I made a small pdf with the necessary settings in the K3 to
operate Pactor. I can say it works excellent if you do it right.
