Which is why I like Echolink. You can do it from anywhere at
any time as long as you have a PC and a microphone. From the
office for example, or home. Although I am generally
disappointed that so many people use Echolink from their
arm-chair PC's without any RF, it does have its advantages.

Agree. I was thinking about the on-line Echolink ability to
contact the repeater from any PC...
In fact, this gets me on my soap box that Echolink and APRS
should be tied together. I have been touting this since 2001.
That is... We can do it now... All we need is one person to
write the code that:
1) Knows where everyone is by APRS (watching the APRS-IS)
2) Knows where all the Echolink nodes are (watching the E-link
3) Monitors APRS messages for any request to TALK to another ham
4) Sends out an APRS message to caller and callee telling them
what node is nearest them (including freq and tone)
5) The kenwoods and Yaesu APRS radios can AUTO-TUNE to those
6) Sends out a link command to establish the two node links.
7) The users talk.
The only thing the original requester did was (from his radio
front panel) was send a MSG to "ELINK" with the words "QSO
W3XYZ" all the rest can be automatic. See
Kenwood and Yaesu have done their part of the plan, but I still
need someone to write the AVRS engine to glue it all together.
Think of it as a ham radio cell-phone system, where all you need
is a callsign, not a phone number.
