Hi, I am encountering some problems to interface a Microham Microkeyer interface with my Elecraft K2-100.
While the CW keyer, USB to RS232 converter etc. work just fine, I am unable to use the interface for digital modes / audio recording audio using my PC's sound blaster. I am using a Microham's supplied cable (schematic can be found at: http://www.microham.com/Downloads/DB37-EL-K2.pdf ) and the constant level audio is taken from J5 on the K2's main board (balanced audio output) as per Microham's instructions. Unfortunately, this level seems to be insufficient to drive my sound blaster input: I have fiddled around with settings, used both MIC and LINE IN inputs, tested the microkeyer in loop mode as suggested by OM7ZZ (the interface seems to be OK) but without results. Hooking the MK input to the headset jack works OK. Before I go ahead and build an audio amp with a LM386 or similar device, has anybody been successful to get the K2 + MK up and running for digital modes as described on Microham's documentation? Suggestions? Ideas? Thanks and 73 Roberto, IV3IYH Elecraft K2-100 #4189 ____________________________________________________________________________________ Don't pick lemons.
