Paul, Try a null modem adapter. For my first attempt, I just connected up the 3 wire cable that I used to control the RX340. It didn't work, but when I put in a null modem adapter (which essentially
Boy, 2 el on 40 at 120 ft and 6 operating positions for a casual opertaion. I'd hate to see what happened if you got serious about things <g>. KLM is gone. M2 antennas makes some replacement parts fo
I received my HP Z3801 last week. To keep things on topic, the intent is to use it as an external reference for my RX340. I mounted the antenna over the edge of my garage roof. That was the easiest p
Dave, Yes I did try reception directly in the shack and no joy. My shack is in a corner of the basement with four poured concrete walls (great tornado shelter) and no windows, so that wasn't too supr
Well, I got things working! I took a piece of RG8X because I had it some and attached BNC connectors to both ends after running it through the house band board into the shack. I used an old PC networ

This raises an intersesting question. Given that these filters are now used as roofing filters rather than as IF filters, will the Inrad 400 Hz filter work properly when the Orion is expecting a TT
center the thought the slope of the Orion filters was adjustable (similar to the sharp and soft filtering available in the Icom 756 Pro II). I don't have an Orion, so I can't check it out. Mark
Jerry, All it is is an optical encoder, no additional circuitry.The terminals on the encoder connect directly to the 25 pin connector on the back of the Omni. Of course, it's probably nicer if there
Mark, There is a 'Keep Alive' feature where the Pegasus will go out of TX if it doesn't receive communication from the host computer within a short time. As documented in the Programmer's Reference G
Mike, Is this knob an optical encoder that can be turned infinitely in either direction or does it just move one revolution (i.e. a pot)? Any idea if two knobs can be connected at the same time? 73,
What I found interesting in the ARRL summary of the FCC was that the FCC denied amateurs the LF allocation as they were concerned about interference to power line communication. Obviously, the power
Timely post. At the Dayton Hamvention yesterday, MFJ had a table selling discontinued items. One of the items was some NOS (new old stock) Telex 'Contester' boom headsets. I have used Telex headsets
