Hi Mal,

If you did some tests today I missed them. While I was out I lost power to both Rx's which I set up to monitor & capture. In addition to the grabber Rx (JRC NRD-345) & Mini-Whip active antenna I had my Kenwood TS-440 & transverter with my 137kHz 12m Marconi for comparison.

When I returned this afternoon there was no power to them.

I will report when I capture your signal again.

After some mods to 137 TX testing observations on DK7FC es G4WGT GRABBERS look good.

Are u seeing any hum now Gary, psu running cool and plenty of decoupling on the Decca tx module, about 400W out to antenna.

My home brew TX  and PSU delivers at least twice that power.
