Hi, I'm going to use my K2 with KAT2 internal ATU to operate a doublet from 80m to 10m including WARC bands without a balun. Among others, Dave's W8FGU home page inspired me to try this.
I hope this is not a problem, especially when battery-fed during portable operation, as there is [almost] no HF-connection to the ground (the whole system is 'floating') Quick modelling of 2x20m + 13.5m feeder antenna shows that KAT2 should be able to do the job, as its 20uH and 2400pF are enough on all bands. My question is: can/should I make it easier for KAT2, e.g. choosing other antenna or feeder lentgh or maybe adding/removing a piece of feeder on some bands? Are there some proven length to use? 73 Oleg _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
