Re: [Elecraft] RX antenna (K3)
The DXE NCC1 is also a nice unit that gives the ability to adust the phase between two rx antennas. I use one with two of the clifton labs active antennas and also installed two of Jack's new HP filters in the NCC1 (It has provisions for filters but DXE decided not to build the filters). 73 Greg AB7R On Tue, Jan 11, 2011 at 7:21 AM, Craig D.

Re: [Elecraft] Data modes issue
Had a similar problem once. Somehow the mixer volume setting for the signalink was reduced. It needs to be turned all the way up. I'm not home right now but go to control panel, audio, it probably shows whatever the default soundcard is on your system. Change that to the USB Audio Codec. Open the playback settings and make sure the slider is all the way to the top for volume. Don't forget to change the default back to your system soundcard or your computer audio will come out from the Signalink. 73 Greg AB7R On Sat, Jan 8, 2011 at 11:31 AM, Joe Subich, W4TV wrote: > > Are you sure you're hearing the audio from the K3 monitor and > not from other speakers attached to the computer?

Re: [Elecraft] AFSK
Wes is correct. Please make sure you check: 1. Baud rate on the K3 should be 45 (if that is what your software is using) 2. If you have the mark freq set to 915 Hz (pitch) on the K3 then your soundcard software for RTTY must also be 915 Hz. 73 Greg AB7R On Fri, Dec 17, 2010 at 9:51 AM, Larry K1UO wrote: > > I'm unable to transmit an AFSK signal in DATA mode, although I can transmit > via the same LINE IN > in DATA A mode.

TWO complete sets. $800 for both Custom KK1L dual band decoder box. See the pic on my QRZ page. This has TWO complete boards installed. Controls two bandpass filters AND 2x6 external antenna switch. Includes FSK keying interface for two radios. Horizontal LEDs show the status of the bandpass filters and the vertical LEDs are for the antenna selections (auto or manual). Ask for more details. $325 73 Greg - AB7R ab7r at cablespeed dot com 360-320-3436 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Numbers, Numbers, Numbers
Playing devil's advocate here folks have often lauded the K3 for being at the top of the Sherwood list so it was fine to "go by the numbers" then. So we should not discount them now. To me...the two radios seem almost dead even. That saidI still prefer the K3 by far due to it's modular design, ease of repair (simple board swapping), service, feature growth and the dedication of the owners and engineers who brought this fine radio to life. I suspect that when customers report glitches on the FT5K it will be quite awhile before new FW is available for download. Ohthere's the money thing too. :) 73...enjoy your radio..whatever you have Greg AB7R On Thu, Dec 2, 2010 at 6:59 AM, Lee Buller wrote: > > Some people here on the reflector have already stated this...but what do > the > numbers from the Sherwood web site really mean?
