The result of having way too much time on my hands but as of right now
VA3QV/m is as good as I see it being.



VHF/UHF communications provided by my Yaesu FTM7250D which along with being
dual band its also dual mode (FM/C4FM) with output power being up to 50w.Â*
If the repeater I am on at the time is part of the Wires X network I can
also access that network as well



HF Communications (15m/17m/20m/40m/60m/80m) with my Yaesu FT450d along with
a Wolf River coil.Â* The FT 450 has a built in Auto Tuner which I plan to
use to extend the bandwidth of the antenna system but so far it has not
been needed



In addition I have a hotspot that I tether to my cell phone that interfaces
the 7250 with the System Fusion system for Wires X style linking

But getting back to HF Mobile operating

In anticipation of next year being better than this year is turning out I
decided to outfit my truck with a good selection of communications gear so
that if we are allowed to travel unrestricted next year communications home
from wherever we were visiting would be possible

It did take a few remakes but the Wolf River 10-80m coil along with a 90
inch stainless steel whip is working better than expected.Â* I am making
contacts (on a daily basis) with stations across Ontario/Quebec and the
Maritimes on 40m and 80m ssb. I have also make contacts into Canadas
western provinces using 20m and 40m ssb.Â* In eastern Ontario the guys say
that my mobile is almost as strong as my fixed station setup seeing that I
have to use a stealth antenna here at home to keep the condo board guessing.




Left pic shows the mount that failed and the one that is stronger is on the
right

Now if you decide to go this route for your mobile I do recommend going
with a very strong mount on your vehicle.Â* My first mount failed due to the
flexing issue with the 102 inch whip (I later cut it down to 90 inches due
to height restrictions) and a 16 inch coil driving around the streets of
Kingston.Â* Before then the coil was working fine and then the mount
failed.Â* After replacing the mount with one more robust it is working just
fantastic.Â* I still have some filtering to add to my ignition and charging
systems as there is some alternator whine and ignition noise there but Ive
got time before 2021 to get that figured out

The next part of the package will now to get the trailer set up and then
make it Radio Active in time for Field Day and the RAC Canada Day Contest.Â*
The next 2 weeks are going to be a busy time.
