I have a 1000MP serial number 6D070234 and can confirm that the top band
spurious problem DOES exist.
A careful check on a separate TS-830 with the 1000MP running barefoot, shows
that between 1820 and around 1830 there is a spurious output. The separation
from the main frequency gets greater as you go up the band:
Main Spurious
1820 1824
1821 1826
1822 1828
1823 1830
1824 1832
1825 1834
1826 1836
So for one khz change on the fundamental, the spurious moves by 2khz. The
strength of the spurious varies and is strongest around 1822/1828 as mentioned
in other submissions.
Incidentally, my 1000MP, as delivered, would not transmit below 1830 and gave
the 'Off-Band' indication. It is necessary to run it in either general coverage
TX mode or 'USA mode' in order to activate the TX below 1830. Was this a
simplistic answer to a Yaesu recognised problem??
