>
> The KSYN3 (older synth, used on the K3) uses a more traditional PLL with its VCO running at the target output frequency. It normally settles in under 5 ms. It can take a bit longer depending on the actual PLL voltage and VCO frequency. This is accounted for in firmware.
>
> If your KSYN3 were not properly calibrated, you might see a longer settling time on one or two bands, most likely 6 meters. If you suspect this, refer to the CONFIG:VCO MD menu entry. The K3 includes an automatic VCO calibration routine that requires no test equipment and takes only a couple of minutes to run.

>> OTOH, the OO's report was strictly advisory. I have experienced spurious OO reports over my >50 years of pounding brass, and one that turned out to be accurate when I blew the filter caps in the transmitter and did not notice, nor did the stations I was working report the hum on my signal. When I got a "chirp" report one time (on a homebrew rig) and was unable to hear it myself, I sent a friendly letter to the OO. He replied that he was "almost sure" he could detect a "slight chirp" so he sent the card.
>>
>> So my advice is that if you can't repeat what the OO observed, don't worry about it.

>> 4) I?ve intentionally ?mis-tuned? the amp just in case that is what was going on when the OO noticed the chirp. I did this by tuning up properly at 14.001 and then QSYing to 14.083 and transmitting while monitoring with a different receiver. No chirp, clicks or other anomalies. This is a much worse operating condition than I normally encounter. It?s so easy to tune the ACOM that I keep it properly tweaked. Also, I was operating in CW SS and in the middle of a 2 hour run when the OO heard me chirping and I have a tough time imagining that I?d sit on a given frequency for two hours without making sure I was properly tuned.
>>
>> 5) I do not use ALC between the K3S and the ACOM. I do run with specific power levels on each band (great feature, BTW) such that I?m not able to overdrive the amp.
>>
>> 6) I?ve checked my in-the-shack coax jumper cables and I don?t see any issues. The antenna end of the coax is currently under 2 feet of snow so I haven?t looked at it. But, I?m getting normal SWR readings here in the shack. There isn?t any arcing going on or the amp would shut down. No RF in the shack; no TVI or other issues in the house.
>>
>> 7) I recently made 535 QSO?s in NAQP CW and did quite a bit of listening on a second receiver, never heard a chirp. I wasn?t using the ACOM so I ran the K3S at 100 watts. And, finally, I have not yet received another OO report after the NAQP. ;-)

Some are running vintage rigs from the WWII era in which a little drift and chirp are normal which usually results in a long rag-chew about the rig since I, too, love vintage gear. Among the others, I don't know if any of them ignored me but everyone said they greatly appreciated my report.

>>
>> 4) I?ve intentionally ?mis-tuned? the amp just in case that is what was going on when the OO noticed the chirp. I did this by tuning up properly at 14.001 and then QSYing to 14.083 and transmitting while monitoring with a different receiver. No chirp, clicks or other anomalies. This is a much worse operating condition than I normally encounter. It?s so easy to tune the ACOM that I keep it properly tweaked. Also, I was operating in CW SS and in the middle of a 2 hour run when the OO heard me chirping and I have a tough time imagining that I?d sit on a given frequency for two hours without making sure I was properly tuned.
>>
>> 5) I do not use ALC between the K3S and the ACOM. I do run with specific power levels on each band (great feature, BTW) such that I?m not able to overdrive the amp.
>>
>> 6) I?ve checked my in-the-shack coax jumper cables and I don?t see any issues. The antenna end of the coax is currently under 2 feet of snow so I haven?t looked at it. But, I?m getting normal SWR readings here in the shack. There isn?t any arcing going on or the amp would shut down. No RF in the shack; no TVI or other issues in the house.
>>
>> 7) I recently made 535 QSO?s in NAQP CW and did quite a bit of listening on a second receiver, never heard a chirp. I wasn?t using the ACOM so I ran the K3S at 100 watts. And, finally, I have not yet received another OO report after the NAQP. ;-)
