2006 ARRL Frequency Measurement Test
This is the first time I ever tried this. It was a lot of fun, and I learned a lot.
I took a stab at the 2006 ARRL Frequency Measurement Test for the fist time this year.
The 2006 ARRL Frequency Measuring Test Schedule
Rig Kenwood TS-2000
Antenna G5RV
I measured my offset using the Canadian CHU Standards on 3.330 Mhz and 7.335 Mhz
I used 2 separate software packages 1 running on a Windows XP laptop, DigiPan, one under Linux Baudline.
The numbers I submitted are the numbers I got from DigiPan. I am still learning how to run Baudline.
The measurements where made by setting the rig in USB mode and tuning down 1000Hz from the expected signal. I let DigiPan tell me the frequency of the signal I was interested in. Simply adding the displayed frequency in DigiPan with the VFO frequency would give me the exact frequency of the carrier signal. I measured both of the CHU standards, and noted the offset.
When I did my practice runs the evening before the actual test my TS-2000 was off more then 400 Hz in frequency. I decided the night of the test to align the rig closer to the CHU standards. I managed to get the rig aligned with in 10 Hz of the standards before the test. This was probably not the time to realign the TS-2000. I took the measurements with the covers off the radio, and after the fact I realized that temperature stability of the local oscillator was probably compromised.
Once I found the signal on the TS-2000 I tuned down in frequency and then I used DigiPan to measure the frequency of the carrier in HZ. I took multiple readings during the test, and pitched out the odd ones. It was a simple matter of applying my offset numbers from the measurement of CHU to the numbers of the actual measurement.
Here are my results, I did not copy 160M or the west coast station.
80m - 3587118.3
40m - 7038806.1
The unofficial published numbers as measured at W1AW where sent to me by Joseph Carcia.
160m - 1854317.5 Hz
80m - 3587117.5 Hz
40m - 7038804.9 Hz
I will update the numbers when I get official numbers from the ARRL.
Not to bad for a first try I was .8 Hz low on 80 meters and 1.2 Hz high on 40 meters.
I did not process the numbers from BaudLine, but I did save them all as audio files. I need to go back and check to see how much difference the two programs reported.
