Re: LF: 8.97kc - TV transformer info needed

[John Bruce McCreath <weazle@hurontel.on.ca>]

Hi Mike, LFers,

I grabbed one of my many MOTs and ran some tests with the primary  connected to 
a signal generator's 600 ohm
output and the secondary connected to a VTVM.  The measured L of the primary is 
.047 H and the secondary L is
16 H.  The turns ratio (120 Volt Primary) is 1:18 give or take a bit.

With the signal generator set at 10 volts RMS, the secondary voltage was 
measured at 1 kHz. steps as below:

Freq. in kHz.   Sec. voltage

          1                     120
          2                     150
          3                     190
          4                      250
          5                      210
          6                      160
          7                      140
          8                      110
          9                        85
         10                       60

The results are poor, just as you found Mike, so it looks like we can rule out 
using MOTs for Dreamers Band.
It's about what one might expect from a transformer designed for 60 Hz. 
operation.
