Hi Mike and the group,
Oh, the reason the antenna is going to the north is that it's the most convinenant direction to run my first beverage. I also tried some RG-11 (also scrap from some CATV company I think) as a BOG. It's about 170 feet (that's what I had) and I used it to just check and see if I could hear better with the BOG using the shield as the antenna. Same results.
I just tried Tree's suggestion and went to the AM band and with the BOG the noise floor goes up on my P3 panadapter. At 1650 KHz I'm copying the local state weather condition and road condition channel. On AM mode it reads 59+5/10 and when I go to RX antenna I get an S-9 static with the carrier visable . Can't hear the audio The AM broadcast station just below at 1640 KHz can be copied. Tried LSB and that noise floor going up is the most noticeable thing going up. Readings about the same.
I even disconnected the antennas getting S1/2. Found when I connect ground on either XFRM input I go from S1/2 up to S-4/5.
