Can lrl frequency be read?

I think the same guy who invented the Gold Gun had a later unit called AGR, something like Advanced Geophysical Receiver. He claimed the local AM radio station can reflect a signal off a gold target. The radiated signal is a lower frequency for gold you multiply the AM frequency by 0.01754 and tune the receiver to this.

So if you follow the AGR theory, 2.113 MHz would be the source of your 68.4 KHz. I looked and could not find any radio station at thtat frequency (at least around here) so my thinking is you did not get something right. One possible explanation might be the iron is alloyed with some other metal enough to shift the frequency. I doubt this, but metals refined before 1960 or so had a lot more impurities. So possibly you were detecting some gold in the iron 68.4/0.01754 = 3.9MHz. Again I don't know what source that would be as I could not find any radio statio at that frequency.

Mike for gold is 0.01754, but what is the data for silver?Originally posted by Mike(Mont) View PostSo if you follow the AGR theory, 2.113 MHz would be the source of your 68.4 KHz.

If you go by the logic that the target responds best to the strongest energy source, then the GG/AGR theory makes good sense and you take a multiple of that frequency times the frequency factor. Earth's field is not the strongest.Originally posted by Pahom View PostThanks Mike! I think the readings will differ slightly from the location due to the diversity of the earth's magnetic field.
