[Elecraft] Re: (Elecraft) SSB microphone question

[Robert C. Abell]

Hi Jeff,

You will need a microphone with lots of gain. I use the Elecraft (Heil) 
MD2, which I believe is still available from Elecraft at a reduced price.

What crystal filter bandwidth did you use in your KSB2 adapter?  I 
widened the bandwidth in mine to 2.2 kHz by changing capacitors CA & CP 
to 39 pF;
CB,CN Open; CC, CM 27 pF;  CD, CL Short; CE, CK 39 pF; CF, CJ 100 pF; 
CG, CH 39pF.

Also be sure to use the Filter alignment instructions in the KSB2 manual 
on pages 19 & 20 to set up your filters.

I do not need a pre-amplifier, and get excellent reports from around the 
world with my K2/100 S/N 4031 on SSB, which incidentily is the only mode 
I use.

If you need help give me a call on the land-line (519) 656-9940.
