.....and NOT a TS-990 - something better!
Just to put some perspective on things, this is a small CW transmitter that just about anyone could build for a few pounds only and use it to work stations all over the world with a modest dipole antenna or similar. The OXO transmitter was designed by GM3OXX and is a classic design.
Power from the OXO is around 800mW - 1.5W depending on the band and on the final transistor and its emitter resistor. I have used this design on HF and had hours of fun with it. Long after a rig like the TS-990 would be gathering dust, this little beauty will carry on giving pleasure with each and every contact.

I had the great pleasure of QSOing GM3OXX and his mighty 1-watter on 20-meters a couple of times. Very good cw signal. Couple of his cute QSL cards too. A real gentleman.
Another QRP classic the Oner is featured the February issue of Practical ( COTPW by G3RJV) The VN10K Mosfets are now obsolete and hard to find and can be substituted with 2N7000 or BS170 Mosfets Iin parallel.

There are some very good circuit ideas In this months
Practical Wireless. by G3RJV well worth the read.
