Hi All..
Just found this list and seems like the only sort of forum on the net to
do with LF!
I'm just looking into 136kHz and looking for a few pointers..
I've temporarily built a loop similar to G3LDO's super loop (but not in
the pvc tube) and got it resonant but cannot tell how high Q it is..
Only equipment i have that will check the loop out is a DDS wobbler unit
that i can connect up across teh pick up loop and see it is resonant
around 136-138kHz...
I'm feeding the loop into a simple sa612 mixer and 100kHz LO and sending
the IF into the sound card at 36-38kHz.
I've only got basic knowledge of home brew stuff so looking for a simple
setup to get me receiveing to see if it will be worthwhile making a
transceiver for the band...
So far I've not seen anything on the band apart from qrm...hi
especially on 137.4 +/-100Hz a noise band that is always there.
Are there any beacons active all the time or is there anything just
outside the band i can look for to check the system is working?
When are the best times to find stations active?
Any comments welcome!
Thanks
