The main station will consist of a Collins KWM-2A transceiver, Collins 51S1 receiver and 312B4 station control.  A Collins MM-1 mobile microphone and astatic D104 microphone will be used.  As backup (in case the KWM-2A gets washed overboard) a Kenwood TS120V HF transceiver will be taken along.  Some QRP Morse code operating will be done using this set.  The antenna for all-band operation (excluding WARC bands) is an inverted V covering 80 to 10 metres.  A Jasco (South African manufactured) crank-up 15m mast will support the inverted V.  If space permits, a 30-L1 linear amplifier may be included.  In addition, a Collins 637T-2 will be taken along for possible portable work from remote points on the island.  For maritime mobile operation, the equipment will be a Racal TR48S with 13 foot whip or a TD-1 dipole antenna (as supplied with the Collins CC-3 carrying case).


Operating Frequencies:

After several requests, notably by Hans Hjelmstrom (SM6CVX) and Frank van Dijk (PA7F) we will include the WARC bands!




















We will listen 5 to 10 kHz up except on CW.  CW will be slow CW, about 15 wpm.  If you reply with anything much faster, you will be ignored! (not because you are sending fast, but because I read slowly).  After some advice by Ron Wright, ZL1AMO (who says we will be the laughing stock of the whole ham world, if we ignore CW operators doing more than 15 wpm), I am now raising this to 16 wpm!  Well, we won’t really ignore the fast guys, I might just not be able to read you… Ron says any fool can yell into a mike.


Depending on band conditions, operating frequencies may change a bit to avoid QRM.  Basically, we will be guided by standard practice as far as operating, calling and simplex frequencies go, see for instance the web page by AC6V.
