[Elecraft] Re: radios on networks

[Larry Phipps]

As I mentioned earlier, I have been doing this with all my shack 
equipment for many years... it is nothing new. The devices required to 
do it were mainly invented for the Point Of Purchase (cash registers, 
credit card readers) and industrial control markets. My units are all 
Lantronix, but another popular brand is Digi. They range from embedded 
PCBs to converters in a socket to multiport boxes. I have one I bought 
on ebay which provides 8 serial ports from one ethernet port, and cost 
me $30.

I like this approach for remote control because it eliminates the PC and 
its maintenance. There are also inexpensive devices to provide streaming 
VoIP over ethernet from companies like Sippura and Cisco, using "analog 
telephone adapters" aimed at the Vonage type internet phone market. This 
allows a remote setup with just a router and broadband modem of some 
sort. The rig, rotator and other equipment appear as remote "virtual" 
com ports over the internet.

As Simon pointed out, latency can be an issue... especially with Yaesu 
rigs, but my experience with Kenwood/Elecraft has been fine. Using a PC 
as the remote host also works fine and many people use both types of 
systems now... but either way, a serial port on the rig is a perfectly 
good, simple and reliable way to interface the rig.
