Re: [Elecraft] [K3] Matching 5 pole filters in main and KRX3

No, you need to use the same offset values for the same filter position in the main and sub receivers. If the marked offsets aren't too far apart, you can use the average of the two values for both receivers. That works fine for my 500hz and 200hz 5-pole filters. 73, Barry N1EU k5oai

[Elecraft] SMD resistors for K3 Line Audio Output mod?

The K3 Line Audio Output mod described in http://www.elecraft.com/K3/mods/K3_AF_Stage_Upgrade_Instructions_Rev_B.pdf calls for 51-ohm 1/8 watt SMD resistors. Can anyone provide a manufacturer or Digi-Key part number, or the correct SMD package size? Thanks & happy holidays, Barry

This seems to come up every year after the ARRL 10M contest. Perhaps an extra 10dB of i.f. gain on 10M could be programmed into dsp firmware. 73, Barry N1EU Jorge Diez - CX6VM wrote: > > We heard two or three very weak signals from PY in the TS850 that were not > heard

Knut, does that Spectrum Lab software allow you to do time averaging for the plots? If you can average over 500+ samples, it will smooth out the plot and make it more useful and readable. 73, Barry N1EU ab2tc wrote: > > These two links show the noise > spectrum of the receiver in US

Re: [Elecraft] An AGC story

is group: is it possible to raise the AGC Threshold from s3 to s6 or s9 by simply reducing the RF Gain control? Can anybody estimate what settings of the RF Gain control would accomplish that? Barry N1EU -- View this message in context: http://elecraft.365791.n2.nabble.com/An-AGC-story-tp5817486p

Re: [Elecraft] AF Limiter (was Recommended AGC settings for separation of signalsin CW pile-ups)

It is fundamentally essential to use very high isolation headphones to achieve K3NA's dynamic range goal (i.e., to hear the weakest and strongest signals with AGC OFF without kicking in the limiter). It IS achievable. It's not a matter of sensitivity. Barry N1EU Dave Hachado

Re: [Elecraft] Recommended AGC settings for separation of signalsin CW pile-ups

even signals of greater than an S-unit difference in strength cannot be discerned. Weak and strong signals are all blended indiscernibly together. Barry N1EU (bottom posted to first show context of response) -- View this message in context: http://elecraft.365791.n2.nabble.com/Recommended-A

Re: [Elecraft] Recommended AGC settings for separation of signals in CW pile-ups

honestly doesn't help much with the pileups. Perhaps it's just the nature of K3's A/D/A. I've used both the K3 and Orion in ARRL160 this weekend and my sense is that the similarly rx gain optimized Orion does a bit better in those situations where there are multiple callers on fr
