Maarten, I found just the opposite having compared my K3 with two separate 7700's with the K3 winning out each time.
Also my wife being a non Ham picked the K3 audio over both of the 7700's each time. 73 de KE4WY Jim -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Maarten van Rossum Sent: Sunday, April 05, 2009 4:58 AM To: Elecraft Group Subject: [Elecraft] My K3's hissy and noisy audio Hello everybody, During last CQ WPX contest I got the chance to put my K3 to work at our contest station PI4DX. We participated in the Multi One klass which allows us to use 2 radio's, one running station and one multiplier station. We used my K3 on the running station and a Icom IC-7700 on the multiplier station. This was actually the first time I could compare the K3 to a high end transceiver such as the IC-7700. I was surprised to find out that the 7700 sounded much better. The receiver was less noisy an easier to listen to. Several other operators also stated the K3's audio was hissy and sharp and not nice and smooth. We could hear it using the built-in speaker as well as on a Heil Pro Set Plus. The RX EQ is flat and I used the 2.7 filter on a 2.7 KHz bandwidth. Narrowing the bandwidth makes it worse but that is to be expected. No NB or NR was used. AFX on or off makes no difference. In addition to the 2.7 KHz filter my K3 also has the 2.1, 1.8 KHz and the 400 Hz filters. It doesn't have the 2nd receiver, the KXV3, KBPF3, or the KTCXO3. It does have the KDVR3, KAT3 and the KPA3. (will order a KXV3 module shortly) After reading all these glowing reports on the K3's smooth receiver I can only draw one conclusion; there must be something wrong with my K3. What could it be? 73, Maarten van Rossum PD2R ______________________________________________________________ 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 ______________________________________________________________ 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
