Yes, even the old model goes to 900Mhz. All of them, even the crappy clones on ebay, work
JUST FINE and VERY accurately on HF, and more than enough to align band pass filters and other types of work on HF frequencies. I am amazed and what this thing can do on HF for $50. Just amazing...
And educational too. At DC to 300Mhz, the accuracy rivals very expensive HP / Agilent Gear.
At 1 Ghz, um, not so much. But at DC to 450Mhz Mhz, this thing rocks...
