Re: [Elecraft] Frequency Accuracy and stability

I tune to 10,000,002 and adjust REF CAL for 20 beats in 10 seconds, or as close to 20 as I can get, with the granularity of the ref cal steps. In the last ARRL FMT, all of my measurements were within 1 Hz, using only a K3 without even a TCXO. Dave Hachadorian, K6LL Yuma, AZ -Original Mes

Re: [Elecraft] Frequency Accuracy and stability

Lou, I find that viewing the output on an audio spectrum analyzer (I use Spectrogram) helps, one can see the beat to a lower frequency that normal hearing.  Just watch the amplitude of the signal - when the beat goes to as close to zero as you desire, you are "there".  I have found that I can

Ronnie, Yes they do, but due to Covid-19 and short staffing, it may take a while. If you did not direct your email to supp...@elecraft.com, it may take a while to get it from one email address to another until it finally hits support. 73, Don W3FPR On 5/19/2021 6:22 PM, Ronnie Hull wrote: D

Re: [Elecraft] Frequency Accuracy and stability

I count beats.  One beat in 1 second and I'm off 1 Hz.  One beat in two seconds and I'm off 1/2 Hz.  Easiest done if the side tone and received signal are adjusted to be close in amplitude and there's little/no QSB.   Zero beats, and the frequencies would be exactly the same, but the practical l

[Elecraft] Frequency Accuracy and stability

I ordered my K3S with "KTCX03-1-F TXCO 1ppm f/w correction to 0.5ppm".   K3S-F s/n 10163 I use CW mode and CWT mode and tune to each of the WWV frequencies.  By pressing SPOT the radio resolves to the WWV frequency but will show any error either + or - of the WWV frequency.   By tuning up abou

[Elecraft] Funny K4 Story i.e. SWR

Most all SWR meters relative instruments.  Meaning they provide an indication in terms of ratio of one value of voltage to another value of voltage.  Thus better described as VSWR indication. As to measurement of power, most all are calibrated to operate in a 50 ohm circuit.  Departure from 50

[Elecraft] [K4] First Impressions of K4 SN122 (LONG!)

I put SN122 through its initial paces today. Here are some of observations: Appearance and general behavior: 1. This is a very good looking radio. The front panel design looks great. 2. The rear panel has more room than the K3. 3. The BNC connectors protrude farther out the back panel than the K3

Re: [Elecraft] Funny K4 Story

Well a meter calibrated for a 50 ohm system will give you a relative indication, but accuracy will vary with the actual VSWR on the line. The further off of 50 ohms the less accurate it will be. On Tue, May 18, 2021 at 7:15 PM Tom Azlin W7SUA wrote: > I put my meters between my KAT500 and the an

Re: [Elecraft] K3 Problem, VFO Noise While Rotating On 10 Meters

Hi Paul Thanks for the reply. I have the upgraded SYN-3A synthesizer and the rig came from the factory with the resistor and diode mod installed.  The clock rate is set to SP2. I should have mentioned that info in the original post. 73  Randy In a message dated 5/19/2021 7:02:19 AM Pacific Standa

[Elecraft] K3 Problem, VFO Noise While Rotating On 10 Meters

Based on the description of your rig, you have the original synthesizer(s). The noise mod involved adding some resistors and diodes to the K3 main board at specific spots and making some firmware adjustments. On the assumption that you have the resistors and diodes already, per your descripti

[Elecraft] K3 Problem, VFO Noise While Rotating On 10 Meters

When I tune the VFO knob on 10 meters I hear a scratching type noise.  This problem only occurs on 10. There was an Elecraft mod that addressed this issue for early serial number K3's but my K3 is a later  unit with the mod built in at the factory during production. Can anyone shed some light o
