[Elecraft] Interfaces

2011-01-11 Thread Edward R. Cole
I am glad that I started soundcard programs way back before 
commercial interfaces were born.  It is so simple to make.  I bought 
two 600-ohm pc board 1:1 audio transformers from RS and one 2n3904, 
some resistors and caps.  That was to set up my FT-847 on psk-31.  I 
then used the interface to run the WSJT suite of programs.

When it came time to interface my K3, it was way more simple: connect 
line-in and line out audio with standard computer cables and connect 
a RS-232 patch cable with sub-D 9-pin connectors.  Of course I have a 
computer with a RS-232 serial port and run winXP.  I guess it you are 
using a brand new win7 quad-core computer with only USB ports it 
might be more difficult.  You would have to get a USB/RS-232 cable.

I have more problems with finding the dialog boxes in the computer to 
adjust audio in/out levels.

[Elecraft] Interfaces

2011-01-10 Thread Don Cunningham
I am not what you would call a "computer guru", in fact not really very 
computer literate at all, but having used the MicroHam MicroKeyer II for 
several months now it seems VERY easy to interface to my station.  I switch 
back and forth between three radios, K3, Yaesu, and Icom, and find all I 
need do after initial setup is change the cable and "fine tune" settings to 
match the particular radio.  It couldn't be any simpler.  Later I will add 
the PW-1 to the mix and be able to use it with any of the three rigs.  I do 
use FSK religiously for RTTY, so don't face the audio level problems there, 
but PSK-31 does and I didn't have any trouble there either.  It DID take 
reading the manual and playing some initially, but once the "language" of 
the supplier is known, and the peculiarities of the rigs are known, it is 
pretty simple.  If I do run into a problem that I cannot decipher, the 
manufacturer is quick to reply with suggestions and page numbers of the 
manual, so I can learn what I did wrong.  I like that approach (i.e., I am 
NOT told the RTFM, but given better clues).  I have no connections to 
MicroHam, SignaLink, etc etc, but feel their interfaces receive a bad rap at 
times.
