Subject: LF: WSPRing on 137 = with new Hafler amp set up

 

Hi All,

 

I'm giving my new hafler audio amp set up a try out on 1= 37 WSPR.

 

IC706mk2G as an exciter (puts out about 100uW on 137), f= eeding into 1.5W broadband amp off ebay as per Dave Pick's article in Radco= m.  New chokes fitted 600nH.   This then feeds into the unbalanced input of the the Hafler P4000.

 

The output is a 4:1 step up txfrmr wound as per the &nbs= p;plans on the W1VD webpage.   2 lots of 16uF caps feeding into t= wo 7 turn coils of coax wound on 77 material ferrite toroids (I didn't have the cores to hand).

 

The coax cores then connect to a balun assembly made usi= ng 77 material cores and this goes to the antenna.  =

 

The whole assembly steps up the impedance from the speak= er terminals from 12ohm to 50ohm.  The impedance was measured as 195oh= m vs a 50ohm dummy load (4:1)  and is broadband from 50khz up to 1mhz. DC resistance is 2 ohm.

 

The amp is rated at 500W for audio and de-rated by 3dB @= 137khz.   

 

I'm currently WSPRing on 137.5.=
