A very promising lrl

[Geo]

As i finished (for this year) my jobs at my farm, started a new project.
It promishes very good details.
This week i will finish it and if weather will be good then will go out for tests.

Take a photo from prototype.....

Best congratulation for your new LRL Geo.



Looks promising, in your style.

Hi Dragan

Nothing special.
No stimulator only one RFsnifer with 55 DB gain and one magnetis detector with 80db gain. Every detector has its own antenna. It needs null between antennas but not so big problem as at Alonso's PD.

good luck

thanks...

The new lrl stayed to the promises .
For unknown reasons the two ics of the magnetic detector burned
Now i must looking for buying new from ebay since they are very old ic's....

Sorry Geo what happened to your devices

[Geo]

Magnetic receiver must have 85db gain but this has only 20db, so today i ordered 2 new ICs from ebay and believe i will receipt them after 10 ... 15 days.

At what frequency your magnetic receiver is tuned ???

Thank you

[Geo]

It is broadband...

Hi Geo.

Why your magnetic detector must have almost 18000 times amplification ? Why not 100dB - 100 000 times? Maybe it is upper threshold for stabile work ?

Thera are many new very high band OP amps with open loop unity gain beyond GHz. Why don't use some of them as input frontend?

Can you share us your RF sniffer schematic ?

[Geo]

It is very simple!!!! because i had the pcb with the 2 ICs with total gain 85db at 100+ Mhz.
The problem is that i can't give full gain because it beeps

[abdou2014]

just this portion, otherwise what's the point ??? i hope it will work for you !!!

thank you mr GEO
