Good morning Wayne, You mention, "(if a KAT4 is installed: ANT 1/2/3). So the KAT 4 is not included in a K4?
On your K4 page, under "Specs", "Standard Features", you list "KAT4 ATU: 10:1+ range; 3 ant. Jacks". Your photos all seem to show the KAT 4 installed with no disclaimer about any accessories being included in the image. Which is it, included in the K4 or not? BTW, there is at least one other place in the K4 page that indicates the KAT 4 is included in the K4. Also, is it true that the K4 has just one receiver? 73, Harry K1RSA -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Wayne Burdick Sent: Tuesday, May 28, 2019 11:54 PM To: [email protected] Cc: Elecraft Reflector <[email protected]> Subject: Re: [Elecraft] K4 RX antenna ports > n6wg <[email protected]> wrote: > > There are 5 rx ant ports on the K4, 3 UHF and 2 BNC. I've seen no mention of how they are to be selected though. In my imagination, I see pressing the RX ANT button putting a list of up to 5 antennas on the screen. This is pretty close, Bob. There are actually four antenna controls on the K4: ANT (tap) Selects the transmit antenna (if a KAT4 is installed: ANT 1/2/3) REM ANT (hold) Might be used to control a remote antenna switch, rotator, etc. (future) RX ANT (tap) Selects the main RX antenna (default: TX ANT) SUB ANT (hold) Selects the sub RX antenna (default: TX ANT) When you tap RX ANT or hold SUB ANT, you'll get a pick list of all available antennas for that receiver. In the case of the K4D or K4HD, you can make independent selections for these, because they both include the diversity option module (with a second ADC, second set of band-pass filters, and separate set of of RX antenna relays). The default antenna for both receivers is the selected transmit antenna. This means the signal goes through the KAT4 ATU and its antenna switch (ANT 1, 2, 3). The other possible receive antenna choices are: RX ANT 1 RX ANT 2 (which doubles as XVTR IN) Either of the two KAT4 *non-transmit* antennas ANT 4 is reserved for use with the future VHF/UHF module. The connector could be UHF or N. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
