Re: [Elecraft] [K3] K3 in diversity mode
Hi Jorge, I was using five different antennas during ARRL 160 for receive. The main Tx antenna (72' Marconi), a 40m vertical, 40m delta loop, 80m Marconi (45') and a 330' beverage. QRN was not horrible during the contest but we did have a storm front rolling through the area and regardless which combo of antennas I used in diversity there was an improvement copying signals. I'm not sure how this will work in very heavy QRN, but suspect it will still provide an improvement over listening on just one antenna alone. It is a fun feature to use. 73, Julius n2wn Jorge Diez - CX6VM wrote: > > Hello, > > I read very positive information about diversity mode, that you can use > two > different polarization antennas to better performance, or just the TX > antenna and a beverage, right? > > But I have a doubt. > > What is the field experience when using the main TX antenna and a beverage > and you have a high QRN? > > Still useful the diversity mode or just is better to RX ONLY in the > beverage? > > Thanks! > > 73, > Jorge > > -Mensaje original- > De: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] En nombre de Richard Zwirko > Enviado el: Martes, 08 de Diciembre de 2009 08:14 p.m. > Para: k2vco@gmail.com > CC: elecraft@mailman.qth.net > Asunto: Re: [Elecraft] K3 in diversity mode > > K2VCO > > Vic, >Thanks for the info on how to correctly get into the DIVERSITY mode on > the K3.

The RX 4SQ has better F/R than my TX array so I use a Beverage and RX 4SQ in diversity RX. You must have the KXV3 for RX ANT in as well as the AUX RF for the KRX3 to be able to use two RX antennas. 73, Bill -- View this message in context: http://n2.nabble.com/K3-in-diversity-mode-tp4130190p4151629.html Sent from the [K3] mailing list archive at Nabble.com. __ 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] [K3] K3 in diversity mode
Hola Bill! Thanks ! And can you setup to have two RX antennas for listening on diversity mode or always one of the antennas must be the TX antenna? So, you TX in the inv-V and listen in one beverage and in the RX 4SQ array in diversity mode. 73, Jorge CX6VM/CW5W -Mensaje original- De: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] En nombre de Bill W4ZV Enviado el: Viernes, 11 de Diciembre de 2009 12:04 p.m. Para: elecraft@mailman.qth.net Asunto: Re: [Elecraft] [K3] K3 in diversity mode Jorge Diez - CX6VM wrote: > > > I read very positive information about diversity mode, that you can use > two > different polarization antennas to better performance, or just the TX > antenna and a beverage, right? > > But I have a doubt. > > What is the field experience when using the main TX antenna and a beverage > and you have a high QRN? > > Still useful the diversity mode or just is better to RX ONLY in the > beverage? > Hola Jorge! You should at least be able to hear something of the desired signal on both antennas for diversity. Then you may hear the signal changing between antennas to help reduce the effects of QSB. However if you cannot hear anything of the signal on one antenna, then there is no advantage to diversity. I have two TX antennas for Topband...a directional vertical array (similar pattern to a 4 SQ) and an inv-V up 30m. I also have many Beverages and a RX 4SQ array. I try to pick my best 2 antennas and use those for my diversity inputs. Sometimes Topband signals are switching between high and low angles and sometimes azimuth directions, so it depends on the specific situation what combination is best. 73, Bill -- View this message in context: http://n2.nabble.com/K3-in-diversity-mode-tp4130190p4151465.html Sent from the [K3] mailing list archive at Nabble.com. __ 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 No virus found in this incoming message.
