Hi Nevell,

FYI my one delivers almost  +5dBm on 50 Ohm.....Ref Voltage +4,86 Volt.

Rgds  Ernie.

Got my replacement FE-5680 and a MV89 in from Nichegeek.  I figured 
'd better power up and check the MV89 before I let 'em know 
verything was ok.  The MV89 is warming up nicely, the current is 
own to 290 mA (and still dropping), but the output seems low; about 
0 mV RMS as measured on a scope with a 10Meg 10x probe.  (Datasheet 
pec is +7 +/- 2 dBm.)  The output is too weak to reliably trigger my 
345A counter.
The reference voltage measures 4.90 VDC.
If anyone can make a quick measurement on their MV89, I'd appreciate it.

hanks!
