During the build of the Band Pass Filters it has become obvious that my little miniVNA is just not up to the job. Because of this (after some advice from Bob 5B4AGN) i will be embarking on building one of these

It’s an N2PK VNA, a very accurate VNA, i suspect i will be unable to beat it’s peformance unless i have a spare £30k lying around. The boards and parts have been ordered so watch this space for progress updates once the parts arrive.

More details of the N2PK VNA can be found here
