Re: [Elecraft] Elecraft gear relative IMD

I have some of those data, but not all. This conversation had already given me the idea that I should remeasure the two radios' IMD at different voltages, as well as vs power vs. frequency. But you are asking for two different things, IMD and spurious signals. With a nominal "12 V" radio, ab

At one time the RS-232 spec did have a distance rating (probably in the RS232A time frame, it was at least 100 feet as I recall). By the C revision, this was replaced by cable capacitance that the driver could feed. In practice RS-232 can regularly drive several hundred feet of cable, depending

While the spec for serial is about 8ft, I run it much further in professional sports timing. Give it a try and see if it works. If you can keep the baud rate down, that will help. To really do it correctly, you will want to run rs232 to rs485 converters and that will certainly solve your pro

A couple of possibilities: Use a USB/Serial converter at the tuner end and employ a USB over CAT5 extender device/cable to get there. CAT5 cable is cheap. There are also RS422/RS232 converters out there. RS422 is good for about 4000 feet as I remember and the converters are not very expensive.
