[Elecraft] [K3] Roofing Filters

Re: [Elecraft] K3: Peculiar BW behavior?

Thanks to all who responded. The problem appears to be solved now. I used the utility to check things out before making any changes, and all was as it should be. However I reloaded the current release firmware, and increased the insertion loss compensation on the 0.40 roofing filter from 1db

[Elecraft] K3: Peculiar BW behavior?

Greetings,   I just came across what seems to be a rather peculiar operational quirk in my K3/100 while reducing the BW on CW.  I have 13, 2.8, 1.8 and 0.4 roofing, running current firmware release suite.   On 20M CW for example, as I reduced the DSP BW down, and as I hit 0.20 the signal

Greetings,   I'm going to purchase a solder station, probably one of the popular Weller or Hakko units, with additional tips.  Both manufacturers sell accessories to calibrate the stations.  Some recommend performing a temp calibration whenever you replace the tip or the iron.  All well and

[Elecraft] K3/100 Assembly - Initial test Cals

Greetings,   I am just starting the initial test and cals portion of assembly, prior KNB3 enable and KPA3 installation.  Power-up went fine with no errors.  Before I start with Synthesizer Cal and move on, is now a good time to update the firmware to latest release, then do all the cals?  I'm

[Elecraft] K3/100 Assembly - KSYN3 Installation

Greetings,   Ref: K3 Kit Assembly Manual, Rev. F, October 28, 2008.   I was just about to install the KSYN3 (ref manual, page 50) when I noticed that one pin on P73 on the KSYN3 board is missing.  Looking at the figure on page 50, it is the third pin from the right, top row. The pin comes off

[Elecraft] K3 - Diversity Reception, Matched Roofing Filters

[Elecraft] K3 Assembly, Resistance Checks

Greetings,   K3/100 assembly in work.  I just did the four resistance checks that verify the power buses are not shorted to ground.  All R measurements exceeded the minimums specified.  However, that kind of leaves a big range of what constitutes nominal values.  Can anybody provide what are
