472kHz transverter repairs

Just after tea last night I replaced the PA in my transverter.  It was damaged when my loop was broken a few weeks ago in the gales. Soldering is much harder these days.

Although it is replaced, the antenna current is still low, so more investigation is needed.

UPDATE 0910z:  I tried the earth-electrode "antenna" on a different rig on 160m and was still getting a high SWR. This suggests something is wrong outside still. More investigations needed!

UPDATE 1725z: A visual test indicated nothing untoward. Possibly tomorrow I may replace the wire in case there is something not visible that is wrong. I measured the DC resistance and this was higher than I was expecting, but not exceptionally high.
