Agreed. 23 cm analog voice, done right, is more potent than VHF or UHF with a power

I always recommend to put a router in between the radio and the computer(s). There are a couple of benefits. * If it is a dedicated router, then you can setup the IP address and never worry

Hi Al, and the group, I have spent some time in the parking lot of the nearby HRO store in Salem NH, and my measurements agree with your results. One advantage is that it sits in the TCP stack, so

Al, You are absolutely correct. Compare this to Wi-Fi and it definitely loses. BUT, AFAIK, this is the only Amateur Radio Only commercially available high-speed mode that we have available, unlike

I think a lot of people have been disappointed with the DD mode's data rate, and the 70 to 90 kbps rate via a DD gateway is typical of my own experience also. However, a 70 to 90 kbps data rate is

You have the speed about right- 90kb or so. It is half duplex. We are big fans for DD mode for several reasons 1. Zero interference 2. Huge power output (legal 10+ watts) 3. Good RF design- we run

Weather maps (we had a big storm here a while ago - SkyWarn was all over it) are interesting - the old ones are not useful and you really almost want to stream/multicast new ones. We have not tested

The question is not if the unit has failed, but if the unit is in range of an "access point" (DStar repeater, Mesh node, or 4G wireless tower) at any moment in time. I've uploaded a diagram of the

Haven't you heard of a firewall? They are fairly new but I think they'll catch on I use m0n0Wall on a WRAP board for NJ2MC's Internet access. We get the usual script kiddies and DOS attacks but it
