Update 27 June 2007
At last I have made the time to re-calculate the prices of the equipment to take into account the work required to meet the R&TTE Directive. The prices as shown below and are effective immediately.The RSL Transmitter has been post designed and tested in accordance with ETS 300 447. Account has also been taken of the facilities required of RSL transmitters in the OFCOM Engineering Code sections 2 & 4, and also the OFCOM RSL information document Section 9 Appendix II Technical Conditions.
Band II Broadcast Transmitter, Economy
Band II Broadcast Transmitter, Rack Mount
Antenna, Meters, & Cable

Audio bandwidth 50Hz to 15KHz with pre-emphasis. Built in mono compressor and peak limiter. Built in SWR meter and output power monitor. Two part painted aluminium case. With 1/4" audio input jack, ON/OFF power switch and LED, out of lock LED, PWR/SWR switch and cal pot on front. SO239 RF socket, BNC RF sampler socket, BNC AF monitor socket, DC input connector, and fuse holder on rear panel. Supplied with 1 metre DC power lead. £335.00. Power supply 13.5V 2.5A £20.00. Optional, XLR female connector and balanced line transformer input £21.00.
Transmit
Amplifier 25W, two stage amplifier tuned to cover a 3MHz
portion of the band, typically requires only 400mW to produce 25W output and capable of
running continuously at 32W output. Harmonic attenuation to better than -60dB below the
carrier at full output. Diecast box with large extruded heatsink that runs at about 40 C
in continuous operation, ON/OFF toggle switch and LED on front. SO239 input and output
sockets, 1metre twin DC input lead and fuse holder on rear. £120.00.
