Re: [Elecraft] K3: Problem with CM-500 plugged into front panel through AD1K

2014-01-22 Thread Jim Brown
This is really a VERY simple problem with a very simple solution. You buy a mic connector that mates with the K3 mic connector. You buy a cable-mount female 1/8-in RTS jack. May make a short adapter cable using a short piece of single conductor-shielded cable, like RG58. On one end, you solder

Bill, Are you certain about that? Bob Heil has told me in the past that none of his adapters have blocking capacitors. 73, Don W3FPR On 1/21/2014 7:50 PM, bill conkling wrote: The AD1K has a DC blocking cap built in. Plug it in the rear jack or use the battery box provided with the CM500

Stan, Try a test - put a bare stereo plug into the adapter and check with your ohmmeter to see if there is continuity between the ring and the shell of the plug. If so, that is the reason - the adapter is using a mono jack and the CM500 has a stereo plug. The tip and ring of the CM500 mic plu

Use an Ohm meter and see if pin of the Foster plug is connected to the center pin of the 3.5mm jack on the AD1-K (DC connection). It is entirely possible that the adapter has a blocking capacitor as the AD1-K was designed for use with Heil's dynamic microphones which do not want DC on the mic ele

Does anyone have any ideas why my Yamaha CM-500 microphone won't work when plugged into the front of the K3. I am using the Kenwood AD1K adapter and I have the firmware set to select the front panel, low gain, with bias on (FP.L bIAS). The CM-500 headphones are plugged into the Phones jack on the
