Helllo Uwe, LF
I am very happy to report my FIRST 500khz RX. As i still finish my
137 khz antennae i did not have any kind of antenna for 500khz
i joined this LF group few days ago and saw that the number of "500
khz" posts exceeds that one of "137khz" so i decided 2 days ago to
fix quickly
indoor antenna i.e several turns of wire on a square-shape paper box
resulting in inductance of abt 0.580 mH series tuned with variable
capacitor and raising impedance ferrite transformer. i put this antenna
into my 746pro trx and the rest is obvious. antenna is "sitting" on
the carpet in the middle of the room
yesterday you posted mail concerning the DI2BE beacon so i used your
frequency of 505.140 khz and the result is attached as the jpg
screen capture frm spectran. also below you will see the DI2AM beacon
transmitting actually on higer freq abt 505.183 kHz ( "left" injection)
anyway, Uwe , i am very happy ( almost like a kid, hi hi) to get my
first observation of radioamateur actvity on 500 khz it happend it was
"your" beacon
my loc jo91rs so it gives abt 700km

p.s. originally, this post contained bigger picture and was sent to
Uwe who pointed out the max size of attached pictures .sri and tnx
for this remark
i hope this time it reaches the LF group. ( first thing first.....)
