Def worth a mention...
Got one to recommend to purchases of my TX's and was most interested to see the response supposedly worked down to 1.6MHz.
I also sell a 3W carrier MW TX and was hoping it worked as low down as 1.4MHz, well it does giving the correct SWR & power readings.
Normal (CB type) SWR meters haven't got enough sensitivity to work at low frequencies without transmittting 20W or so (have tried).
So this device is ideal and doesn't need calibrating, just plug in-line and Transmit thru' it, Simples...
