Icom D-Star Terminal and AccessPoint Modes

ve3ips

If you own an Icom  radio that supports Terminal and AccessPoint features (currently, the ID-51A Plus2 or the ID-4100A), the following may be of interest to you.

 Terminal and AccessPoint modes only work using ICOM Callsign Routing. This means when you connect to another gateway via you radio’s Terminal mode or AccessPoint mode over the internet, you will be heard there, but users who want to reply will need to know how to use Callsign Routing and capture your callsign (usually by pressing the radio’s Callsign Capture button while you are still transmitting).  If they don’t do that, you will not hear their reply.  The same applies to when you want to reply to a callsign routed call.
This means Terminal and AccessPoint features do not support linked connections to reflectors.  REPEAT:  The new Terminal and AccessPoint modes do not support linking to REF or any other reflectors.  They…

CounterPoise Directionality with Compromise Antennas

ve3ips

Many compromise antennas are the 6 to 12 foot variety. The Buddistick, SuperAntenna MP1, Pac-12, and a Chameleon (it has various variants) all offer a short antenna with multi band capability.

The key to these antennas is to have an elevated counterpoise. I have done several Field Strength Readings in the field and in a controlled location to try to understand if there is any directionality to its placement.

YES I have found that there is!

Point it towards the station you are trying to work. There is noticeable improvement in the transmit signal that it would be worth the effort to locate the counterpoise accordingly.

I dont think I am seeing much in the way of reception of signals.

A gain of 3 db is the equivalent of doubling or reducing by half your power.

PLEASE NOTE THE COUNTERPOISE WILL WORK A WHOLE LOT BETTER IF IT IS ELEVATED…

“It’s not real Ham Radio!” by Chris G7DDN

(This a a bit of a long read, but it opens up a lot of questions where this hobby is going these days.  Comments are open on this – what’s your opinion?)

A Pioneering Background

I was musing recently on the wonderful history of Amateur Radio, from the early pioneers with spark transmitters and the race to get the first signals across the Atlantic, up to the Microwave enthusiasts who developed the way forward for space communications and satellite technology (and, whisper this, mobile phone technology!)
