DStar Roundtable

      No Comments on DStar Roundtable

Following the 8pm Thursday night net on Dec 14,  we had a DStar roundtable on the W4OVH 2M  DStar repeater.   This was a good opportunity to use DStar radios , find out what was happening with the repeater and make suggestions.   The following stations participated:  Jeff KM4FTK, Ken K1KDA, Ken KE2N,  Jeff KJ4MTP,  Joe KI4OHR, Bill N4SV and Mark WA4KFZ.   We saw Baofang KK4JFK on the DStar radio screen but were unable to get any audio.  We understand she is new to DStar and still configuring her radio. The DStar repeater news was that the linking capability to reflectors has been tested and works on all DStar reflectors (REF prefix).   There are some reflectors (  DCS and XRF prefix) that it does not work on.  The technical committee is working on this.  The linking testing was spearheaded by  the two… Read more »

On November 18,  the city of Manassas and the city of Manassas Park held a joint emergency exercise for their combined Community Emergency Response Teams (CERT).   The exercise was held at Osborne High School and involved finding victims in blacked-out rooms and the triaging and transporting the victims.

The Making of a full size 160 Horizontal Loop

Jeff Fischer, WB4TT, recently decided to add a 520 foot horizontal loop to his antenna farm. Jeff wanted this to be a homebrew antenna and not an off the shelf antenna. He made his own 1:1 balun rated at a kilowatt out of 12 gauge magnet wire over which he applied a 3M coating for extra insulation. With the help of neighbor, Gil Thompson , KM4OZH, he created  antenna mount points for the trees from hardware store hardware. These mount points are designed to flex with the trees to avoid snapping the antenna wire through metal fatigue. The mounts consists of an 8 inch eye bolt in the tree connected to two pulleys. The pulley connected to the eye bolt is connected to Dacron rope that is a loop to the ground to aid adjustment. This first pulley is connected… Read more »
