Roger...(and other perhaps-interested parties on the list)
Good advice. However, I think the dynamic range issue is not of
great concern, since I live in a fairly isolated rural area with no
local VHF/UHF contesters. Moreover, the 910 works into a TE Systems amp
with a GaAsFET preamp in line to improve the 910's not-so-hot noise
figure. At 144 MHz I am not so concerned about line loss, but on 432 I
have a mast-mounted GaAsFET preamp, since the 910 is really quite deaf
on 432 and line loss is more of a problem.
Another factor which is somewhat of an aid is that I don't lie on
the line of sight of anyone ELSE; in particular VT and NH are very
sparsely populated with VHF/UHF stations, and the active Maine stations
are well away from my bearing from just about anywhere. My 10 element 2
meter beam also adds some selectivity because of its directivity, and 11
elements on 432 does the same.
A third comment: I have compared the 910 against the XV144 on the
same antenna and feed line against the stations that are "local" -- the
closest are mostly in the Hartford area 60-70 kM south of me and there
don't seem to be any issues on receive. I have used these two setups
interchangeably for the past several weeks with no noticeable
differences at all, specifically for comparison purposes.
If cost and physical space were no issue, I would probably choose to
run a Kuhne TR144H, but that unit is too costly for me (around 4X the
price of the XV144). I managed a once-in-a-lifetime deal on the ICOM
910H, and with preamps it is a nice little box.
Thank you for the response. I was aware of the advantages of
transverter use, but maybe there are others on the list who will benefit
from your comment.
