[Elecraft] AX1 works great

Some of actually have _negative_ KH1 antenna deployment times. 

Example: While hiking, you see your next destination on a slight rise, graced by a tree just tall enough to afford some shade. You perceive a rapid dropoff in the direction of DX. It's ~40 seconds away, but it only takes ~20 seconds to get the KH1 out of your pocket, attach the whip, unwrap the counterpoise wire, open the log tray, flip the paddle to the operate position, and turn on power.

Net deployment time: -10 seconds. You might even make your first QSO before you get there.

The internal "tuners" - impedance matching devices - of the KX2, KX3 and KH1 allow max energy to be input into the antenna - 5-12 watts. Using the system as factory delivered, I have had great success with the AX1 and the KH1 whip. The internal "tuner" matches the antenna, allows full radio power out and receive energy in. I connect the antenna directly to the radios, push the tune button, get the 1.1:1 match almost always and make contacts. The QSOs are sufficient to activate parks, which has been my goal. I am able to accomplish my goal without putting the AX1 or whip on a tripod, using multiple radials/counterpoises, or using coax. I can setup the radio in less than 5 minutes, spot myself and usually complete the activation in less than 30 minutes (usually, if the sun is cooperatin
> g), and teardown in about 2 minutes. I use an external battery.
> Of course the AX1 is not going to be resonant as presented from the factory, when measured with an analyzer. It is a 4' collapsible whip, with one 13' or 31' counterpoise. Use the internal tuner, attach the antenna to the radio, and have fun. It is about having fun. One of the local hams has fun using random metal objects as antennas. He tuned his antenna, a toaster oven, sliding the tray in and out. He loaded a floor lamp, a screen door, a metal fence - and made QSOs with all of them. Someone mentioned Kurt N. Sterba (and Lil Paddle). They debunked many basic philosophies held for years by hams - tribal knowledge. Ham radio is about having fun. Just have fun. The KX-2/3, KH-1and the AX1/2 help to make ham radio fun.
