Hi Mal, you wrote:


Someone posting here recently said their SPM-12 did not have a freq
locking facility.
My SPM12 has a phased locked loop, with coarse and fine tuning as well
as the main tuning dial, maybe there are various specifications for the
same models.
It has a 10 khz IF output plus other outputs. I built a product det and
the whole unit works well and is very sensitive and selective down to 25
hz. I also use an ext DSP unit. The whole package makes a great LF
receiver and works well also with my receiving loop antenna.

yes, Mal, i have discovered the phased locked loop later, now i have made
some test and i found that the SPM 12 is a very good receiver for LF, and
also the stability with PLL is  good, also it has a very low phase noise and
the option button "low noise input" work very well.
This unit was bought here 2 weeks ago in hamfest for 170 Euro!!

73 and see you on the band.
