Well,
Following all the palaver associated with my Power Meter project; I've finally completed it.
Here's the finished article:
The front panel (which is covered in Fablon) isn't anything like as bumpy as it looks in the photo to the naked eye; it's perfectly acceptable.
I've finally decided that the switches need to switch between short and long sample times (as before) but the second switch that I had used to peak hold the meter, now switches the units primary display units from dbM to dbW - each of these has the power converted to watts in brackets.
The unit had quite a bit of use this weekend in the WAE RTTY contest - and yes I was sending and receiving QTC traffic! - but the meter certainly seems to work at full UK power from my linear, it's a damn site more accurate than anything else I have here, but most impressive was the ability of the unit to read really low reflected powers so I can tune the antenna far better with this unit than I can with any of the analogue meters I have here. This meter can tell be that I have -20dbW reflected power when an analogue meter wont even be moving.... I'm actually quite impressed.
Cat's not overly enthusiastic about it:
Impressive though, egh?
