Hi Laurence,
 
I have tested a 2-30 MHz 1000H  slug on my Bird 43 on 475 KHz = and he=20 need about 2.2 KW
to read full scale on the meter with clean sine wave signal on 50 = ohm dummy=20 load.
I think that not all the H series slug are identical.
The 2.5 Kw slug does not work on 475 KHz.

Steve - using the Bird 43 originally with 2-30MHz 1Kw 1000H insert on = 475kHz,=20 and then compared it with a 1Kw 1000P 450kHz-2.5MHz insert and maybe = (maybe) the=20 2-30MHz insert was showing low about 10% on this machine using 200W = carrier=20 power (clean sine) -

 

Note - Ive been told others have different cal tables and the = differences=20 were larger but I was surprised my Delta was so low between the plug = elements.=20 Measurements were using a Bird 500W Termaline and confirmed with Pk/Pk=20 scope.

 

Im typically using the Dual metered (Phase and Z)  M0BMU Tuning = meter=20 and though for 136kHz gives good results on 475kHz and although it does = affect=20 the termination Z and phase a bit according to the AIM4170 I leave it in = line=20 and not gone thru a pair of FETS for a year or two - Ive not done the = mods=20 suggested for 500kHz as its used both for 136/475

Has anyone here had experience using (or = attempting to use)=20 an HF SWR bridge
on 630m and if so, what did you find=20 out?
