The SK0CT Rover
To promote the microwave activity in the club, we
decided to provide a portable, low power rig for all the popular
microwave bands. The intention is to let club members use the
Rover, preferably in the NAC microwave contests. The Rover is powerd
from a 12V battery, thus making it totally portable. The Rover
further consists of a set of 4 microwave transverters mounted in a
reused TMA-box. The TMA box is in turn mounted on the lower part of the
antenna mast. The fifth microwave transverter, for 24G, is mounted
together with the antenna to minimize the feed loss between antenna and
transverter. On the mast, it is only 130cm tall, are
all the antennas
affixed. There is one antenna per microwave band. |

SM0EPO (most right) shows SM5FDA, SM7GVF and SM0KAK how it works. |
The antenna mast is
fixed on a military surplus tripod with adjustable leg lengts. To make
the tripod truly vertical, a level is affixed
to the TMA box.
The following bands are included in the Rover.
The Rover is prepared to
include the 47 GHz band in the near future.
The main rig is an ICOM IC706MkIIG. Not only the HF bands are available
but also the VHF/UHF bands 6, 2 and 0.7m are included in the main
rig. For the purpose of adapting the IC706 to
the microwave transverters, an extra microwave band selector is added as
well as a TX power attenuator with its control circuits.
If you are interested in operating the Rover, get in touch with
the most frequent users, e.g SM0EPO Per-Olof,
SM0NCL Christer
or SM0DFP Per for more details.
