Hello Brian,
I've done a lot of experimenting with my K2 and the Heil HC5 element,
and I think that some of the reasons for the many degrees of success
using this element are related more to voice charactersitics than to
anything else.
The first thing to note is that the Heil HC5 has been de

I have found the best way to get additional gain from the KSB2 is to add the
KSB2 INCREASED GAIN MOD by KI6WX as well as the other KI6WX KSB2 mods.
These mods can be found on the Elecraft site. Be sure the mike input is
biased
correctly first. Roy Morris W4WFB

Brian!
Do you have another KSB2 you could lend from someone or another proset?
I'm using the MH2 here and even with ssba1 and ssbc1 I can with high
voice(not yelling!) get 100 watts out.
Also see if FL1 is set to OPT1.
And ??? Can it be that the bias resistor is touching ground?

Brian,
Have you checked things on the KSB2 - particularly the resistors (RP5 too)
and the soldering of the Speech processor/compressor chip. While the HC4/5
elements are about 10 dB less than most other mics, you ahould be able to
make up for that with the SSBA = 3 and SSBC = 2-1 pr 3-1.

Both HC-4 and HC-5, select with switch. Both OK for 100W, but I have yet had
to use the squawky "DX" one in battle.

Good thought, but no.

Thanks for the suggestion. I think it's ok.

Bob and Vic make excellent observations about needing to measure TRUE 'peak'
output.
One way you can do that with the K2 itself is to switch the bargraph to ALC
mode (press/hold RF/ALC). Now the bargraph will show you when you've hit
full power output as set by the POWER control and the ALC kicks
Brian,
Before you get too disillusioned with the performance of the K2/KSB2 on SSB
output with the Heil microphone, what are you using to measure the TX output
on SSB?
It is essential to use an RF wattmeter that is capable of measuring true
PEP, not just one of the joke instruments on the

I can get 100 watts by whistling loudly into the mic.

Hi Brian,
I use a HC5 with my K2 and I modded R14 to 5k6. This appears to be
optimal for my setup and I get plenty of audio now into the rig. I am
using a headset though so the mic is
Hi all,
I've got a K2/100 with a KSB2 that I've just installed and am trying
out. My mic has an HC-5. I am aware that this element does not have low
output for the K2. I've done the R14 mod, replacing it with a 10K
resistor. It's working better than it was, but I still don't seem to be
