I got an e-mail from VK3ZL with some pictures of his new topband amplifier.  
You can find them here:

Note that he won first place in the Home Brew advanced category with this.

You can find Bob around 1824.5 kHz most "mornings" up to about 1230 UTC 
when he goes to bed.

The band was quiet last night - I could actually copy W1AW - but no sign of
the 7P here.
