Thanks Doc. Are these the signals from a single antenna or from two? If from a single antenna, this sounds like Digital Signal Processing. The Elecraft K3 has a function like this that I've never tri
Thanks for the info. The best bet for saving bucks on a K3 or K3S is to buy one of the used K3s that are coming on the market as guys replace theirs with the new K3S. And the best way to find one is
Hi Greg, IMO, the KIO3B is NOT an important upgrade. The USB interface is a convenience. The serial port on the original KIO3 is just fine, USB to serial adapters are inexpensive, and excellent USB s
Not true. The signal processing described for what these folks are calling "binaural receive" is somewhat complex, far more than a polarity reversal of one channel. Since I own radios with this proce
Kim is almost right in that it is TIME that gives us the most powerful directional cues. Amplitude differences between ears is second. The low pass filter to one ear and high pass to the other does b
Look for a speaker that fits in the mounting space. The speaker that Elecraft uses for their K2 and K3 is quite good for its size. It's a 4 ohm speaker, and NY9H told me many years ago that he found
Hi guys, I bought the RSP-1 several months ago, primarily to use as test equipment. I haven't really put it through its paces in a serious way, but it is clearly worth the $130 I paid for it from HRO

Right. And my guess is that many countries no longer honor them. Best bet is to take those that are not expired (check the expiration date on each one) to the post office and turn them in for interna
I've not looked at one, but everything I'm seeing is that the 7300 looks a lot better on paper than they do on your operating desk, and their price has fallen like a rock. If I needed an HF rig in th
Two points. First, NOWHERE was it stated that a hole should not be drilled in the pole. Second, the website stated that "These are extremely strong poles, with a much greater wall thickness (up to 2m
That's a very nice amp, Ron, and Bill's a great guy -- we've been friends for more than 30 years. I'd grab it! I bought his Titan, and it has served me well. And a used Titan is the other amp I would
Doesn't quality matter? I've owned the original Herc, two Herc IIs, and three Titans. I still own the Titans and one of the Herc IIs. All are VERY well designed products. Their only negative when com
In a few of the high profile DX contests, there is a move afoot to require logging of the exact transmit frequency. The concern is that some are violating the rules by operating out of band. But as o
