KE4WY: Never any desensing in the presence of strong signals observed with my K3.
KA1J: I noticed no desensing with the K3 in the presence of strong signals. I agree. 160 is the ultimate test for dynamic range (and desense or BDR) for any rig. Operating SOSB/160 I never experienced *any* desense this weekend in breaking the current USA record by >25%. If anyone experiences true desense (and some don't understand what that means), they don't have their K3 set up correctly. The simple way to do this on any band is to find the *minimum* gain combination which will result in hearing band noise when the antenna is connected (versus disconnected). On 160m, this usually means ATT ON and RF Gain backed off to 12-2 o'clock. For a Beverage only (not diversity), more gain may be necessary (i.e. ATT OFF but no PRE). For diversity, I like to balance the signal from my vertical TX array (about +5 dBi gain) with my Beverages (about -13 dBi gain following a splitter). In that case I use PRE for the Beverage side, but even on my Beverage port I never heard *any* desense this entire weekend. You can make the K3 desense by running with PRE ON and maximum RF Gain, but that's simply operator error and not the fault of the K3. 73, Bill -- View this message in context: http://n2.nabble.com/K3-receiver-desensing-on-CW-during-contest-tp2369819p2384234.html Sent from the Elecraft 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
