I plan to install a digital in/output in my K2. I was lucky and found a no more used EA3BLQ digital interface. In the manual I found two ways to get AF into the interface. One is from the digital audio filter and the other from the RF board J5. As I do mainly Pactor with a Ptc-2 the better way seems to me to bypass the audio filter and get the Aux AF from J5. Is this correct? I don't want digital signal processing on the signal to the Ptc-2. The only thing I need is a 500 Hz bandpass filter for Pactor 2.
I am not very savvy in electronics so I thought I better ask here before I do something stupid. According to the circuit diagram from EA3BLQ I can use Pin 1 and 3 from J5 to connect the digital interface to the K2. This interface seems to be exactly what I need - automatic switching off a eventually connected microphone is a very nice feature which I miss in mny other radios except the Kenwood TS440. btw, thanks for the input on my microphone question regarding the SM-8. all clear now. 73! de Werner OE9FWV -- Fund = give money; amentalism = mindlessness.
