First, the radio sounds great and it seems to put out at least 5 watts, but there are a few problems I have encountered.
- After trying to match the frequency with the Cal jumper in place, the radio is again off frequency after I power cycle it. (about 1.2 KHz high - I can live with that.)
- The BFO is about 400 Hz too high (or 600 if the goal is a BFO frequency of 800 Hz.) My KX2 is set at 600 Hz which appears to be around the peak of the passband on the Hilltopper. If I try to adjust further, the BFO frequency merely starts to climb higher, and farther away from the desired frequency. The trimmer cap I think was all the way down tight. Which way does the trimmer go? Increase or decrease capacitance?
- The gain control doesn't seem to do much. That may have to do with proximity to the transmitter, but it seems it should do something.
- If you overload the front end of the receiver, it throws it into wild oscillation in the ear buds. OUCH!
- I am useless with iambic mode A. I simply can't use it after 35 years of iambic mode B and self-completing characters. Is there a way to permanently set the radio for straight key use? (Maybe short the outer ring to ground?) Because of my other radios I do not have the ring connected (Elecrafts don't like it, except the K2.)
At a minimum, I must get the BFO frequency in the right place to try it in the field.
One more thing - how tolerant is the final to bone headed accidental keying without a load? Haven't blown anything yet, but not wanting to do so either!
Oh great gurus of the Hilltopper, where should I go first?
