I have for sale some fully tested PCB's I made last year;

16Ch DDS, preprogrammed, selectable with DIP switch.

Quad GaN, latest FETs from Transphorm.

NCP81074 fast drivers.

90 % efficient, just needs bolting to a modest heatsink or metal case with small fan.

FETs have grounded tabs so no need for insulating washers etc.

PSU needs to be 48V @ 10A.(+12V@120mA for drivers)

I've had considerably more power from these with 600W @ 60V but things start to get a bit warm. At 400W it can be passively cooled.

ANY 200KHz band segment. (8MHz max)

I'll post up some pics on eBay but thought it best to advertise on here first.

$300 ONLY!

I can provide full instructions etc.

Has been heard in the air with good reports!

You will need your own modulator etc..

'It's better to give than receive' so why RX when you can TX!

                            Buy one from me, NOW!

Great discounts on ALL my transmitters if purchased via HFUnderground
