Operator error. I somehow had Ant 2 selected which begs the question as to how I was receiving signals at all (nothing is connected to ant 2). Selecting the actual antenna and such works 100%.

Didn't notice any difference between the tuner active and tuner bypassed. Tuner insertion loss is in the order of 1.0 dB or less when matched, depending on which side of 50 ohms it is required to match. Very low Z matches tend to show a bit more loss than values above 50 ohms. 73 Bob, K4TAX On 10/2/2015 9:44 PM, Jerry Moore wrote: I only tuned enough to not be on top of the station.

It seems you set / tuned the ATU for a higher frequency, being the 2nd frequency where you listened, then moved back down band with out retuning. It would seem then the ATU would be set for some frequency other than the one you were receiving. Yes, going to bypass might indeed likely show a higher received signal. 73 Bob, K4TAX On 10/2/2015 2:00 PM, [email protected] wrote: I was playing with my K3S listening to code on 40m. I could clearly hear the signal but it wasn't loud. I spun the dial up a good bit and listened, nothing heard after about a minute so I pressed ATU Tune. The ATU clicked a few times and stopped. I spun back down where I was (somewhere around 7.033MHz) and dialed in the signal. Sounded about the same. Just for grins I did a long press ATU Tune (ATU) to BYPASS. The signal immediately jumped over S9 (was around S7 before). That didn't make sense so I repeated the process a few times with the same results. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
