TravelPlus for Repeaters - Multiple Routes n9apd 1 day, 23 hours ago
It is very easy to do multiple but not connected routes or separate point locations in TravelPlus. In TravelPlus we call these Independent map locations or route segments

Once you have created any route which has at least one point, all you need to do is move the cursor to the location you want to place the independent location or route segment, hold down the Shift key and left click. This will place a route circle at this point with the radius you have selected. You may do this Shift / Click to create as many independent points or route segments as you wish. At any new point, you may make it into a route by doing a normal left click from the new point. You can then Shift / Click to create another independent point which can stand alone or become a route segment.

After you have created your independent points or segment (or at any time really) you can modify the Range of any point or route segment by right clicking on the point or segment and adjusting the range.

There is a Help file topic which provides additional information and some map examples. It is in the Working with Maps section and is titled Define Independent Map Locations/Route Segments.

Gamma Match Question KD8ZIH 2 weeks, 2 days ago

In most cases, it is impractical to close off the end of an aluminum tube electrically in a fashion that will hold up to the rigors an antenna must endure.

WINLINK TNC N2PHI 3 weeks, 6 days ago

Pactor is used for HF Winlink nodes, but the hardware modems used are expensive.

There has been a trend to skip using hardware modems and use the computer to handle the software functions of a TNC.

Winmor is a software alternative to a Pactor modem.

On HF, hams will use software programs with a simple hardware interface to operate modes like PSK31, JT65, and RTTY. I've heard that MARS (Military Affiliate Radio Service) uses FLDigi and MT63.

Email forwarding question n1chu 4 weeks, 1 day ago


You should use the account where email is forwarded. It sounds like you have a Comcast account--you should use that.

One Antenna or Two for HF/VHF/UHF pmc181 on 26/9/14

Do you want to talk on the radio? The only HF band that lets you talk is 10 meters--I'd suggest a simple 10 meter vertical or dipole. How loud you are really makes a difference on voice. On data or CW, not so much, so you can make more of a compromise and still do quite well.

You might talk to the locals about the scene on VHF/UHF. In some places, nearly all the activity is on 2M. But, in others, 70cm is also a popular band.
