K3 Noise Blanker

[Bryce A. Carr-2]

 With over 200 on 160 from this 80 ft. wide city lot I take a real interest in noise blankers. A few days ago my friend gave me his K3 kit to build for him. s/n 1487 2.21 firmware with 2.7khz, 1.0 khz, .400 khz filters. His 2nd rx still on order.
Tonight I have it together except for the 100w amp and this evening I was playing qrp and listening to OHR that covered most all of the 40m band and was peaking S9 with my gp ant on 7.070 mhz with 2 khz bandwidth selected.

As expected, the NR button was of slight help with this terrible racket in the audio line but the NB button completely removed it with no reduction in desired audio level. Completely, I mean 100%
The S meter dropped from S9 to my normal KH6 40m noise floor of S5. No trace of it heard with the other filters either.
My K3 is on order.
Congrats to Elecraft. Aloha, Bryce, kh6at

Just curious, Bryce: Where you using the K3's DSP blanker, IF blanker,
or some combination of the two?

*Just removed from my K3 because of a change in my filter lineup.

KFL3A-1.0K  1 kHz, 8-pole roofing filter

This filter was installed a few months ago----in as new condition.

Elecraft wants $125.95 plus shipping and tax (if applicable to you)


This one is $110.00 delivered lower 48.

I will happily deliver to Europe!

Please contact me off-list.
