Intersting ideas. If you did enlarge the SSB board to get all the bits in,
in which directions would you enlarge the exixting board?
IMHO it would be essential to contain the "new" board in a 'tin' box in turn
mounted on metal, which raises the question of access to test points etc on
the RF board,
This is a horse of a very different colour!! We are now talking

Dave,
If you are referring to the Yaesu FT-900 knob, you can find details on my
website www.qsl.net/w3fpr. The smaller F-100 knob (with finger depression)
is preferred by some folks, but the FT-900 knob is heavier and my
preference. I have also seen the Yaesu rubber tire for the FT-900 knob

Yeah, but that looks tacky hi hi. The K2 is more elegant than that. Buy

I completed the transmitter alignment on K2 #4429 recently. In checking the

Ben,
The place where one aligns the bandpass filter on 10 meters must depend on
the 10 meter operating that is anticipated. If the interest is mainly CW,
the bandpass filter would be peaked at 28.2 MHz as stated in the manual --
OTOH, if more phone operation (or CW higher in the band) is more des
I believe that you would be proven correct about the RF feedback.
My thought about a tin box totally enclosing the PCB stems from an
observation that the skirts of the varicap "controlled" filter set for say

I was afraid of that -- I recalibrated the tuner with a 50 ohm dummy

correct. I will further calibrate when I have access to a known

Andrew,
That elusive 'known accurate wattmeter' may be a challenge to find -
especially at the power levels you are attempting to measure. Many (most)
wattmeters spec the accuracy as a percentage of full scale - so if you use
one good for 10% on a 50 watt scale, the error can be as much as 5 watt

The simplest system for receiving PSK31 is just a cable with a 1.8 inch

the other end into your sound card.
For transmitting, you need a cable from your soundcard (1/8 inch plug) to

Probably as you say that a tin box around the whole assembly would be an

out more, and the whole area ground-planed top and bottom. I agree that
