hello speed when Saint-Jean VHF / UHF going back on the server because it is the only station on the Three Runs well to listen to the SPVM or if it is not a configuration problem for the HF station and c for her that makes her what was wrong Montreal Thanks in advance!

You have been warned multiple time as you constantly hijack Tuners. Opening another acount because the old one is banned is not permited here.
As for VHF/UHF will eventually re-open it, but I have no cable to connect the antenna. The cable used for that RX is now used for my icom-706mkIIG

It was a very good idea to change antenna polarization from horizontal before to vertical, thanks for doing it. Here are a few observations on how the Körner 15 element FM yagi antenna polarization change has affected FM band reception.
As many if not most of your local powerhouse FM stations in Montreal use horizontal polarization or mainly are horizontal including a bit less vertical mixed polarization, signal overload across the band has been reduced by a few dB!
Several vertical polarized FM transmitters are now better received.
On 103.1 semi local CKOD using horizonal only polarization is now much weaker (at least -20 dB), f.e DX Signals come in more often, such as WTOJ Magic 103 from Watertown, NY & CFMX-Classical 96.3 Cobourg, ON.
On 88.5 the local CBC Radio 1 station horizontaly polarized, using a verticaly polarized high gain 15 element FM antenna, in a certain direction the signal from the nearby Mont Royal transmitter (max. 25 kW ERP) was weakened enough to enbale first time reception of a verticaly polarized low power 290 watt WVPA-VPR/NPR rebroadcaster from St.Johnsbury, VT.

As some of us know my antenna controller (Version one) had problem this week and I decided to pull the plug on it. I took time to finish the new controller system (Version two). It work really good, will try to do a small video demo for it and try to put it on top of the tower sometime this week.
The new system accurately track the antenna position (+/- 2 degree)
in the mean time, the Korner 15.9 antenna is at fixed 230 degree.

Ok so now I run with the new definitive antenna rotation system. Will have to find time to make an "how to" soon :)
If someone see strange thing happening with the rotation please send me a support message or an email to globaltuners at croisieresrichelieu.ca The antenna setup and tower is expensive, don't want to break thing as the system haven't been tested enough to my taste.
Basic concept:
I still use and Arduino board to control the motor. The board is used to activate 3 relay witch replace the big knob on the indoor control unit the card fit at the place of the knob so everything is inside the control box.
I track the antenna position by using a 10 turn potentiometer connected to the motor gear with a 72 teeth gear (Using something around 60 teeth would have been easier to assemble but I had a 72 teeth gear already). I send 5v on it and read the voltage from 0-5v with the Arduino board. The board sample the voltage with is integrated 10 bits ADC and I do simple math to make 0-1024 appear as 0-360
I have a protection that stop the rotor if antenna doesn't rotate for more than 4 sec. The tracking position is send back to GlobalTuners interface every 900ms. the system as a precision of around 2-3 degree, as the antenna continue to turn a little bit after stopping motor (This is not a 500$ us Ham radio rotor)
The system use 6 wires cable. I use AWG 16. 3 are for the motor and 3 are for the potentiometer.
Hope you enjoy using it and make DX with my FMDX-saint-jean and Saint-jean HF node.
P.S. The antenna rotor is controlled by the FMDX node but both FM and HF antenna are on it, so if you want to rotate HF antenna please use FMDX node. And don't forget to ask before rotating the antenna :) :)

As we never stop working on nodes problem to bring the best we can to the comunity, I have solved two problem that reduced the sound quality (severely).
I don't know why it happen nor since when, but I got a drivers conflict with both m-audio sound card used for nodes (Revolution 7.1 and audiophil 2496). it added a strange rumble sound and some part of control panel crashed when tried to use it. I re-installed both drivers and everything is fine now.
The second problem was the ground from the Icom receiver, hope it's better now.
