RADIOANQ - VERY RARE HAMMARLUND PRO-310 RECEIVER: The PRO-310, manufactured from 1955-57, is the rarest Hammarlund receiver. Only about a thousand of these unusual top-of-the-line radios were made, and because of their $595 price tag and brief marketing life, relatively few found their way into amateur usage. The PRO-310 is a 14 tube general coverage receiver that tunes .550 MHz to 35.52 MHz in six bands. A separate calibrated bandspread dial covers 20% of each band. PRICE: $750. For pick up Greer, SC (no shipping).SEVERAL MORE PHOTOS AVAILABLE - JUST ASK.

RADIOHF - Autek VM-1 SWR WATTMETER: Excellent condition swr wattmeter.
Very accurate.
Includes hard to find power supply
Autek WM-1 Wattmeter
$100 shipped
So, what's the big deal about a wattmeter? Well this one shows you what you want - all of the time. It is called a 'computing wattmeter' because it displays your SWR on one meter all of the time. No forward set and then switch back to read the SWR. The SWR reading is much like the SWR indicator in your rig. No cross-needles to read (though I have a tuner with cross needles and that isn't bad). The right side meter displays your output power - all of the time.
It is an active device so, it does require a 12v supply and needs to be 'on' to operate. The latest models of this meter have backlit meters. It has 3 scales : 20w, 200w, and 2kw. The meter is at center scale for 5, 50, and 500w. The 'Peak' power setting holds at peak power with a slow decay. It appears to be an accurate display of both SSB and CW peaks. The 'Average' setting has very quick res; Listing #1766436 - Submitted on 04/29/26 by Callsign KD8IGK - IP: syn-047-224-077-001.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
