The first time I hooked up 2 rigs like this and listened I was absolutely amazed at how differently they sounded. I've since done this with several different rigs:
TS-830s, IC-735, Omni V, Drake R-4A Drake 2B K1 K2 After all the testing I ended up with 1 rig - the K2. That has since been replaced my the K3. That 2B really did sound smooth & sweet though as did the K1. The rest of the rigs no longer interest me in the least. - Keith N1AS - - K3 711 - -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of dw Sent: Thursday, April 02, 2009 12:37 PM To: Elecraft_List Subject: [Elecraft] Keiths idea on audio test two rigs KEITH THANK!! I do have a small adio mixer I could use! And I could also jury-rig up a switch to toggle the headphones between the two. Thanks Duane Here's my technique: 1. Connect both rigs to the same antenna, through some sort of (jury-rigged) Y arrangement. 2. Feed the speaker outputs from both rigs into separate inputs on my Behringer or Mackie mixer. 3. Set rig's AF gains to about 1/2 way point to improve AF S/N ratio. 4. Trim the inputs on the mixing board to get both channels to the same level. 5. Set both channel EQ control to the same (flat). 5. Plug headphones into the mixer. 6. Tune both rigs to the same signal. Now, to compare the rigs, you adjust the channel volume controls on the mixer. Listen to each channel by itself or put one rig in the L ear and one in the R. You will definitely hear differences that you wouldn't hear if you listened to one rig for 30 minutes, then disconnected, hooked up the 2nd rig and listened for 30 minutes. Oh, wait, you wanted a suggestion that didn't involve any equipment. - Keith N1AS - - K3 711 - -- bw...@fastmail.net ______________________________________________________________ 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
