Having listened to the critics and having invested in some new test equipment I've improved an existing design and also designed something new.
I feel it's about time for an update and to offer my latest TX's
I can now offer;
1; A fully tunable 40W TX using a AD9833 DDS and a Transphorm GaN FET as the main O/P device.
This is totally immune from any FMing issues or carrier drift and is easily preset to ANY frequency you desire!
As it's Class E it's B/W is restricted but will cover the whole of the 43m or 48m band easily.
Needs 24V (26V ABS Max), quite happy @ 12V with 10W O/P. Approx Size & Weight 6"x5"x2". 2lbs
2; A 32 CH 150W TX with PWM mod and built in SWR indicator and protection built in.
Needs 48V to 60V 10A ABS Max (will give 100W-150W) Approx Size & Weight 7"x5"x3". 5lbs
Please PM me if you're interested in either.
'1' is ready but have still to finalise the metalwork on '2'.
'2' had been a labour of love and really wanted to build something that was truly portable and rugged.
ALL the other designs I've seen are in a 3/4 U 19" rack, hardly 'Portable'!
'2' is infinitely more complex than '1' and will be somewhat more expensive!
If you have purchased a TX from me before I'm happy to offer a discount!
