The HF station
The HF station comprises a minimalist approach to the HF bands!
A hombrew 10 watt solid state transceiver (left) is complemented
by a homebrew VALVE linear using a pair of 6146's to run about
60W on 80, 60, 20 and 15m. A 60 foot long wire doublet is used
for an antenna with an old KW E-Zee match unit.
The solid state transceiver is based on the G3TSO design with a 9Mhz IF and makes use of the Plessey series of SL 600 series of IC's thoughout. A basic 5-5.5Mhz FET VFO is used in conjunction with a mixer and switched crystal oscillators to mix to the various HF bands. The output power is raised to the 10watt level in a solid state amplifier which used to be marketed in kit form by Cirkit.
My current activity is on 10MHz on WSPR and BPSK, with some SSTV on 14Mhz.
Recently I have been listening on the 500khz band using the loop shown below, together with a pre-amp and Lowe HF150 receiver or homebrew converter to the 144Mhz band.
A recent addition has been an elderlyYaesu FT77.
