I have been tinkering with Winmor on my fixed base Ham setup to see how it might work and made my first Winmor/Winlink email
connection this morning. Was a very satisfying experience. For the benefit of others, here is how I set up the configuration:
Computer is an HP minitower with an nine pin Com port so that made connecting to ICom
746Pro transceiver fairly straightforward. Connection is made through a voltage converting cable in this case purchased from Personal Database Solutions in Auburn GA. I think the cable was around $25. Runs from COM1 to the CI-V RCA jack in the back of the Icom
to transmit control instructions.
Next piece of gear
needed is a Tigertronics Signalink-USB external sound card. Winlink's website www.winlink.org
makes it clear that getting good transmission
quality is a lot easier if you have full control over the audio levels coming out of the computer and driving the transmitter. SignalinkUSB is around $100 but very well built and supported.
Icom runs into a simple wire dipole that works best on 20 meters which is fine because that seems to be the best band for daytime propagation these days anyway. Lightning
arrestor and a 4:1 balun were the most expensive parts
of the antenna
Icom must be placed in USB DATA mode or there will be NO AUDIO at the ACC-1 jack that the Signalink plugs into. Found this out the hard way.
Once I found all the various configuration screens and setup menus between RMS Express (the email client) and Winmor (the software
equivalent of the very expensive Pactor Modem
which I am resisting investing in), it was time to find an open Winlink channel and send my first email. My first attempt on 40 meters didn't work. Quickly shifting to 20 meters, to my amazement, my four work test message went through in about 120 seconds and the software
disconnected! Holy email, Batman!
I was a little nervous when the email didn't show up in my terrestrial inbox but I had a feeling it might take a while to the first email to propagate through the Winlink system. Around 60 minutes after disconnecting, there is was.
The only question I have is with respect to speed. I know Winmor is not going to be able to keep up with Pactor 3 or even Pactor 2 for that matter but the maximum throughput recorded by the software during my transmission
displayed at 406 bytes/MINUTE. That's pretty slow.
Anyone have real world experience with a well connected Winmor system who can tell me what I should be able to see in terms of speed?
Also happy to share any other configuration questions people might have. CF is a terrific resource and I've gotten a lot of helpful info here.
