[Elecraft] K3 as WSPR transmitter

[turnbull]

Dear OMs and YLS,     Wht not just run 100mW to a Watt?    Surely then there is no heating problem.   I ask because I am starting the process of using WSPR on my K3.   73 Doug   EI2CNSent from my Samsung Galaxy smartphone.

Even before I installed the 100W amp card. I have never had any problem with the low power amplifier (LPA) with those modes. I have also run those modes at 100W with the KPA3 with no problems. I don't think you'll have any problems with the 110.6 second WSPR transmit sequence.73 Bill AE6JVOn 1/5/20 at 4:54 PM, pfizenmayer at q.com (HP) wrote:>I see the lore is that the LPA does not care for long key down >periods - I was toying with using my K3 as WSPR tx on 160 and >80 fpor some antenna evaluations. .>The lore would say its not a good idea ?>The manual is not clear to me of whether in fact there is a 160 >low level out I could use for a home brew external amp -The >KIO3 transverter bands show 160 coded -but other tables talk >about just IF of 7 mhz and above.>BUT its all moot of the LPA is still biased on and limited in key down time ?????---------------------------------------------------------------------------Bill Frantz        | Re IOT: "How many access control systems does it takewww.pwpconsult.com | to change a light bulb?" - Dean Tribble______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to turnbull at net1.ie
