Temperature, the best friend of LRL's

[Geo]

Hi.
Today i tried for second time a new LRL. It is a simple magnetic field detector with some modifications, plus a fm tuner as Esteban shows many times. First time i went to a place with some copper coins burient 18...19 years ago.
No results. It was a day after rain with temp about 25o Celcius.
I went again today at 18:00. Temperature 38 oC. Yes.... i received a lot of signals around 3...4 m. Beeps was from MFD and not from radio fm because every time that i had beep, i had indication from the leds. Beeps was random and short, no continued. So the problem was again the same, no way to pin-point. But with this temperature, something is happening. It is the first time that i took signal from copper with lrl of this technology.
I went again at 21:15. Temperature was 29oC. No beeps . The first led sometimes was light but no beeps. Maybe the out of MFD want a little modification so the beeps to coming easy when the led light a litle.
But the resume is one. With big temperature the "magnetic field" is more strong than it at lower temp.
