I just take a look to the website. It costs 300 Euro which is not to much. The whole kit looks very high quality and the functions are FB. Also the power ranges. Normally i want to build my own equipment but here i may become weak :-) Also the PA design looks very interesting to me. They say 14V/5A for 60W, i.e. about 85% efficiency. The FETs is use are ordinary TO220 devices. Looks all very interesting. I will take the idea of the "current mode class D PA" and play arround with it... For this power level and frequency, ferrite transformaers can be very small, unusual when coming from 2200m :-) 73, Stefan/DK7FC Am 30.05.2012 19:45, schrieb Warren Ziegler: > Uwe, > > The Juma 500 is a FB little transmitter, lots of built-in features > (synthesizer, keyer, swr bridge, receive preselector, receive > converter) in a very small package.
