Hi John
Good guess at both my range of interest(indeed below 900MHz) and the education side... I have very limited techniques as im new to it all.
Im going to try and find that article you mention, if not il try to buy an old hard copy of the mag on ebay.
Re the loads, you are referring to the three calibration connectors provided correct?
Would making my own finer tuned ones be a realistic task? as in components, pricing, and skill?
If not if you know anywhere to buy some finer tuned I would appreciate the link
Thanks for the help!
