[Elecraft] Heil HC4 Element - Audio Increase - K2

[Sara, VU3RSB - India]

Hi Friends

Need a help for my Elecraft k2 SL No:2569. I have recently converted my HC4
- Head set in a Microphone with Sewing Machine paddle as Foot Switch.

Connected Audio - 1 PTT - 2 and 7 & 8 as Ground in the 8-Pin DIN Connector.
HC4 is giving low audio. When i compare with Dynamic Microphone is giving
good result (Yaesu MH-31 Converted for K2). HC4 is not giving the good
output audio. I remember frank, DL4KQ gave me the modification document
which i lost. Can any one guide me on the modification of Resistor to
increase level of audio for HC4.

With Diagram and modifications would helpful to fix the problem.

See you soon from IOTA.

Regards
Sara, VU3RSB
