STATION EQUIPMENT
The Kenwood TS-830s is mains powered and uses valves in the finals, it covers the H.F. bands,
1.8 to 29 Mhz including the WARC Bands, Modes are SSB & CW ( No FM ) at 100 watts output.
Its an early 1980s rig, but still very popular, just Google "Kenwood TS830" for information.
The Yaesu FT-726r is mains or 13.8 volts powered, and is intended for the VHF bands.
it will accept up to 3 of the available modules ( 10 mtrs, 6 mts, 2 mtrs, & 70 cms ).
6 mtrs, 2 mtrs, & 70 cms are fitted. All modules give 10 watts output, Modes are SSB CW & FM.
Its an early 1980s rig, just Google "Yaesu FT 726" for information, specification etc.
The Trio 9000 is a 13.8 volts powered 2 metre rig. 144 to 146 Mhz, 10 watts High & 1 watt low.
Modes are AM, SSB, and CW. Its a early 1980s set with synthesizer control.
The Moxon is a 13.8 volts powered 4 metre rig. Ex PMR 16 Channel, FM only.
I have no further information on this rig, ( neither can I find any )..
The Central Console enables the selection of any rig, thereby switching the Speaker,
Microphone, and Key to the rig, the second station speaker may be switched to any other rig.
The first speaker may be switched to headphones, with provision for two sets of headphones.
It has a built in CW practice oscillator, which can be switched to replace the Microphone.
Provision is also made to select different Microphones and keys. Additionaly it could also
control the switching of transvertors etc. Rigs etc are switched by the following unit.
The Central Switching Unit has a master switch which operates a mains relay, this switches
on the 10 amp PSU, and the supply for the swivel lamp, and provision for a computer.
The 16 switches for the station equipment control relays for higher power equipment or
switch lower powered equipment direct.
The Home Brew 13.8 volt 10 amp power supply also has +24 and -24 volt low current outputs,
plus the unregulated voltage for the 13.8 supply, this is used by the Central Switching Unit.
It supplies everything except the amplifiers and any rig that may draw over 5 amps.
The + 24 & - 24 volt supplies along with the 13.8 volts are connected to the test sockets.
The Trio R-600 is a mains or 13.8 volts powered general coverage receiver, 150 khz to 30 Mhz.
Modes are AM, SSB, and CW. Its a early 1980s set with synthesizer control and triple conversion.
The Realistic Pro 2005 Scanner is 13.8 volts powered, Modes are FM wide/narrow & AM.
Frequency coverage is 25 to 520 Mhz, 760 to 824 Mhz, 851 to 869 Mhz 896 to 1,300 Mhz.
ANTENNAS
The H.F. Antenna is at a height of about 9 metres. and is cut slightly longer than an 80 metre dipole.
The two legs form an angle of about 120 degrees, due to support location restrictions.
The final 1 metre is hanging verticaly, again due to support location restrictions.
THE VHF ANTENNAS ARE CURRENTLY A WORK IN PROGRESS, THIS IS WHAT THEY WILL BE.
The RG213 co-ax feeders for the VHF antennas are routed through the loft space,
A fixed scaffold pole passes through the roof with a sealed box on the top.
The cables are routed through the scaffold pole into the box, and onto the antennas.
A short length of scaffold is clamped to the roof pole, and can be swiveled down.
The short pole carries the rotator with the antennas directly on top the rotator.
These directional antnnas are for 2, 4, 6 mtrs & 70 cms.
A 2 metre J pole is chimney mounted for the Trio 9000.
A 70 cms J pole is also chimney mounted for the FM rig.
A 4 metre dipole is loft mounted for the Moxon FM rig
A CB antenna is loft mounted for the Midland Alan 78 plus.
A discone antenna is loft mounted for the Realistic Scanner.
TEST EQUIPMENT
The Test sockets use 5 pins, common zero volts, unregulated 24 volts, 13.8 volts
and the plus and minus 24 volt supplies, this enables any piece of test equipment
to be plugged into any socket irrespective of its operational voltage.
Test equipment is fitted with voltage regulators to avoid the use of batteries.
The Unit to Set-Up VHF Antennas is designed for final adjustment following construction.
It is self contained mains powered, switchable from dummy load to antenna, has a 3 Db & 6 Db
attenuator, this helps protect the rig against a bad swr match, the ptt switch has 3 positions,
off, lock on, and press on. With this unit final antenna adjustment can be carried out outside
with the antenna in the clear, but easy to access for adjustment of the matching.
