[TVARC] NanoVna and remote tuner

[Dave Alford]

A big shout out to Joe K9TUW who advised me how to tweak my roof loop that
Jeff KO4NCC advised me to put up.  I first ran 16 ga around the roof..about
190 ft.  probably 100 ft was laying on gutter, remainder over roof and down
roof line.  Used a 4:1 unun.  Results ok.  Reran today cutting down plastic
2in  J hooks for pvc pipe and tie wrapping onto the gutter supports so wire
extended about 3-6 inch away from gutter and roof  (besides blown insul,
attic has foil backed insulation between the rafters).  Following Joe's
advice, I took out the 4:1 unun, ran 16 ga ant wire down to station with 300
ohm old tv ant wire.  I also purchased a AH-730 remote tuner (I have an
IC7300)  from Ed N4EDD  (Ed is selling a bunch of stuff.suggest you take a
look and make his missus happy) and ran the tv wire to the remote.  On all
bands, the IC7300 says my swr is holding less than 1.5.  More importantly, I
am getting out, albeit a little weak, but clear.  I haven't raised my power
out above 60 watts.  I read somewhere that 20m band and having 15-20 ft elev
I should only need 40 watts??????

 

So, having given my shouts to Joe, Jeff and Ed, I also want to thank those
of you who were so gracious to comment on my now old plan of using my palm
tree for a vertical (and I am sure my palm tree adds its thanks) ..amazing
how great thoughts are murdered by bare facts.  

 

Which leads me to this question..in maybe the next year I hope to be
somewhat proficient in cw (or the year after)..I've been told (for what its
worth) most cw is on 40m band.  If so, I want to optimize my loop for
40m.7.1 probably (down by the wiaw).  I have a NanoVNA.  I don't see in user
manual, or on google, if I need to do anything different to check swr/smith
chart/ etc using a remote tuner like the AH-730.  Its seems that I should I
check the parameters on the ant after the remote tuner.  So appreciate
guidance  

 

And I hope to hear from Glenn.I did not catch his callsign..i briefly spoke
with him tonight on 3.589 (?)
