40 meter cq

At last i have made the vu2vwn qrp tx running about 3 watt. It is very stable due to the crystals. Freq 7060 Khz. Keying is also good. Only problem is that it is for cw (A1A). Either it needs to be run into AM (A2A) or DSB (J3A) for voice communications. 

After putting it in a box will try a small linear using  mosfets or may be design a new DSB tx from the scratch.
my cw call will be
