I have just completed a new SSB transceiver that is very easy to build
and fun to use.
It is specially designed for beginners.
Check it out at http://farhan.net.co.nr/bitx.html .

Highlights a
1. Very few coils to be wound.
2. Just 16 common 2N222 varity transistors used everywhere except for
the the IRF510 in the PA.
3. Works without a slow motion drive! Uses two knob tuning for coarse
and fine tuning.
4. Uses fewer different values of resistors and capacitors.
5. Stable design.

I've bookmarked your page and the one you linked to for futher
reference. I'm in the process of designing and building a rig myself.
The final parameters are in flux at the momement. I recently bagged
a lot of 414 8.3688 mhz crystals on ebay (at less than 5 cents a rock)
in HC6U cases. I need to build a sweep oscillator to build a filter
around these cystals. However since my rig will be using an AD9954 DDS
vfo (which HAS sweep ability built in with a ram lookup table) I think
I will be building the vfo / microprocessor section first! I have a
number of PIC chips on order and I am getting the development tools
installed on my Linux box. I'm also in the process of building a PIC
programmer. (Amazing how one project spawns many others!).

I'll probably use a pair of IRF510's in push pull for my final. I've
heard they can produce as much as 40-50w out, but I'll be happy to get
25w. I've been stocking up on -2 and -6 toroids whenever I found a
batch on ebay. I had this crazy idea of building a switchable bpf
into an old TV turret tuner with removable coil strips. The band
switch would be the old tuner, I could add a 12 position rotary switch
to the back and have the micro processor read the switch.

Another FB rig from Farhan! Seeing the new rig perched atop
"Experimental Methods in RF Design" convinced me to buy the book.

My favorite line from Farhan's description of the rig:

"This transceiver was designed during a six hour flight from Europe
with paper, pencil and the basic calculator built into my cell phone.
It was soldered in three sittings over three days. Very little went
wrong during the construction."
