LF: 300W 136kHz TX

[G0MRF@aol.com]

I had a call from Bob G8RW today.

Bob has one of my 300W class D transmitters which he ran as a 'beta test' prototype for me.  

Bob has gone QRT on LF due to the ever increasing switched mode power supply QRM and would like to find a new home for the TX.

The transmitter is housed in an aluminium case apx 12 W  x 6H x 10 D (inches). From memory, It has a fan, 12V PSU for the logic and had some extra protection voltage clamping diodes fitted across the FETs. - I can't remember if there is an internal 30V psu for the FETs or not.......Best check with Bob and adjust price accordingly.
Frequency control is the on-board VCXO but there is an input on the PCB for a DDS etc at CMOS levels.

Price can be haggled, but something around the cost of the TX kit (£79) seems fair as this means you'll save the effort of building it and the cost of the box, heat sink, fan and PSUs etc. - 

Bob's telephone number is  020 8462 1592       QTH is Bromley Kent.
