interesting 10x12 signal readings

[BeachCleaner]

I spent a few hours out with my SEF 10x12 yesterday and during the hunt I played with the RX a little, I noticed the signal readings were extremely low, much lower than the were the last time I played with it, infant it was below 20% with RX =15 and Tx =on so I tried hunting for a few minutes and sure enough it ran smooth with No over load. I don't care to ever hunt like that so I toned it back down. I'm confused now, it like a good coil got better? Anyone experience this or have an explanation for why it would do that, I understand that temperature causes expansion and contraction and can change the null of the coil but the temperature was very close to what it was the last few times I used it.

This is normal for any coil. The conditions just changed at the site. It could have been the ground, EMI, who knows?

My coil is emi sensitive, very. I can tell when the sun is starting to set by the amount of gain I can run, really.

However I still have good numbers and can run the gain high.

I think Rob is right. I never check in those settings too much you know. I only adjust my sensitivity and a filter, the others depends of what you are hunting for. I also stick on the preset programs and I have good results. I hope that helps.

Just got a white sef 10x12 and checked my signal. Had a 25% signal inside my apartment then had a 50% signal outside. Brought it back in and had 40% signal. Waited a little and the signal went back down to 25%. I'm wondering if the coil getting cold caused the change.? Anyhow I might have to go to round two on my SEF purchasing.

At what gain settings?

I had my settings rx-15 tx boost on three frequency. Found 7.5 frequency to have a the highest signal percentage on mine when I checked each frequency individually.

Very few will run that hot. I have run mine at a gain of 12 with tx boost on but the stars and moon have to alligned just right....

I run mine at 12 most of the time with tx off and get some emi from time to time.

I just used those settings to see how well it would handle them. Normaly use RX-12 no boost. Just a short test until I can get out on a real hunt and go somewhere EMI isn't so bad. Just thought it was odd how the coil getting cold made it so much worse. Guess it likes room temperature.
