Nice, Try to listen on 332 kHz for YFM, La Grande 4, Que. This is where the LG-4 power generating station is located and it usually comes in strong.
GW on 371 kHz in Kuujjuarapik, Que. is so far the furthest Northern NDB on the Quebec side that I have listened to followed by YPO on 401 kHz located in Peawanuck on the Ontario side.
