Bill, Never mind on the cheapie DMM link I sent. Looking at the specs, the frequency counter is listed as 10Hz to 10MHz (which means they only claim accuracy within that range).
And, although it *DOES* readout all around 144MHz - reliably (I just tried it again) - it only does so at a resolution of 100KHz, which is definitely not enough precision to perform your PLL alignment (at VHF, I assume). Still, it's pretty cool that such a cheap DMM will freq-count that high, in any event! 73, KF5YHP Sent from my iPhone > On Jun 19, 2016, at 11:00 AM, Ravi Patrick Ratnala <[email protected]> > wrote: > > Hey Bill, > > Wouldn't an oscilloscope be the best tool for the job here? > > Alternatively - I just picked up a couple of these to serve as backups for my > Fluke 117 - only $20, and just horsing around, I've already measured > frequencies up to 144 MHz: https://smile.amazon.com/gp/product/B015OFMUYO > > 73! > > Ravi > > Sent from my iPhone > >> On Jun 19, 2016, at 10:44 AM, Bill Crowell, N4HPG via BVARC >> <[email protected]> wrote: >> >> Howdy All, >> >> Does anyone have a vacuum tube voltmeter that can be borrowed/purchased? >> Including the probe. >> >> Doing PLL alignment and I need to measure at 100MHz.
