FREE Radiometer Copenhagen Wave Analyzer: Something for the collector of the unique, someone interested in vintage/antique audio/acoustics, or maybe someone just interested in the potential tubes/parts content. Full model is FRA2TcAT3a. This is essentially an audio spectrum analyzer that was used for acoustic signal analyses in a testing lab. Vintage 1962-63, made in Denmark. This has been with me for decades, and it's got to go! It's somewhat dirty, but I did a very quick once-over cleaning on the middle section of the front panel & based on that I think it should clean up OK. It's complete, including tubes, but no power cord, no external attachments/accys. The orig. manual w/schematic is included. Last operated ca. 1980, and it worked well then (yeah, I know, "it worked when last used"...). It has NOT been powered up since then, and SHOULD NOT be powered up now prior to having it thoroughly gone through.
This thing is heavy - NO shipping. P/U ONLY at my location in York PA.
Please take this off my hands! It's FREE!!!; Listing #1760461 - Submitted on 02/28/26 by Callsign WB3BEF - IP: c-174-55-147-174.hsd1.pa.comcast.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

For sale:New MFJ-434 voice keyer: This is my personally owned never used never opened until I took these photos MFJ voice keyer-434 I bought new at HRO Anaheim location about 6 years ago. I opened it up for the first time today to take these photos. Its is new not used not slightly used but brand new in the box in my home for the past 6 years while assembling my retirement radio station. However, due to an unseen recent illness (two hemorrhagic strokes) this has left me in a condition making it nearly impossible to continue my ham radio hobby. Therefore I have to sell my entire station down to the bare bones, one radio one antenna. And even thats a difficult time at the radio trying to remember how any of all this works. I take only PayPal and all correspondences are through this qrz site. I pay shipping ups to lower 48 ensured and professional packaged. $225.00 firm. Comes with stock original manual.; Listing #1759973 - Submitted on 02/23/26 by Callsign KD6CCP - IP: customer.snjecax1.isp.starlink.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
