My results came back recently:
| Band | Error (Hz) | ppm Error |
| 160M | 1.22 | -0.66 |
| 80M | 0.59 | 0.15 |
| 40M | -0.69 | -0.09 |
On 160M, there was a far stronger signal level than the other bands, but the results are the worst, probably because of mixed propagation paths, unstable ionosphere, etc. On 40M, the signal was so weak I was not sure if I had it at all, amidst all the QRM. Probably this was ground wave propagation.
The full ARRL report is here.

Hi I would suggest to lock the 44.55 Mhz Oscillator to a 5 Mhz reference. Divide 10Mhz/2.
Than use a CT1DMK (see TAPR site)
Reflock 2 board, Or see VE1ALQ.
Divider N must (44.55Mhz) be set to 891 (-1)
and Diverder R (5Mhz) must be set to 100. Both references can now be compared at 50khz.
The 5 Mhz can be derived from a 10MHz rubidium or from a 10Mhz GPS locked reference.
