I set the tuning power level to 2W to tune my MFJ magnetic loop, but when I used SSB at the weekend to work a few stations in the contest I noticed that the SWR reading was peaking quite a bit. At 2W the K3 SWR meter would never read below 1.2:1. I increased the tuning power level to 3W, and that enabled me to detect a minimum of 1.1:1 for a more exact match, but perhaps there would be more of an improvement to be gained at 5W.
I guess one reason the K3 tuner seems less sensitive to me is that the K2 internal tuner was designed for QRP, 10W, whereas the K3 tuner is the same in both 10 and 100W models. One thing I notice is that the K3 relays whirr whenever you press the Tune button, even if the antenna is already matched, whereas the K2 just transmitted a burst of RF for a fraction of a second, saw it was already matched, and didn't enter the tune procedure at all. ----- Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com Zerobeat Ham Forums: www.zerobeat.net/smf -- View this message in context: http://www.nabble.com/K3-Tuner-Operation-Question-tp15842717p15850023.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
