Hi Bob.? Yes, I discovered that early on.? At 20 meters and above, however, peaking the preselector didn't solve the problem.? While I had carefully aligned the R4C using the Drake recommended technique (soldering in the resistors, etc.), I decided to revisit the alignment this time using Rob Sherwood's suggested technique.? After doing that, the counter works perfectly up to 10 meters, where the injection signal is still apparently too weak.? Next I'll try a buffer amp before the input to the counter.? At any rate, I suggest that anyone using one of these counters with the R4C use Rob's alignment procedure and resolve any issues you find along the way in that procedure.
