Just one additional comment... I cringe when I hear talk about using wallwarts to power the FLEX-1500.
They will work great in receive. BUT the transmitter will work better (stay more linear) with a power supply that does not move up and down in voltage as the load goes up and down. Most wallwarts have high internal resistance as part of their consumer protection. The FLEX-1500, or any transmitter, for that matter, will be much happier in transmit with a regulated power supply. At least with more regulation than most wallwarts provide. --- Graham == On Mon, May 16, 2011 at 5:10 PM, Brian Lloyd <[email protected]> wrote: > On Mon, May 16, 2011 at 1:19 PM, John Stuart <[email protected]> > wrote: > > > > Hi Brian, > > > > Is your “power measuring device” a Saratoga Power Meter (I have one of > those), the PWRcheck from West Mountain Radio, or another device? > > It is from an outfit called Medusa Electronics but it is very similar to > both the Saratoga Power Meter and the PWRcheck from WMR.
