RADIOHF - Anan G2 and Orban Optimod 6300: 3 year old Anan G2 operated on Thetis, thinning out my inventory ...I recently received an Anan 10e so I don't need this radio also. Has Noctua quite fan installed, case has a few scuff marks from moving equipment around but generally it was out of site anyhow, all controls are on the PC side. PLEASE do not buy this if you are not familiar with the Anan G2 operation of shut down and the use of Thetis. These are NOT for the un-skilled beginner user, try a Hermes radio first at the $400 price range. $3050.00 shipped
Also letting go of my Orban optimod 6300 audio multiband compressor, limiter, & eq. This can be usd on your TX audio and on RX audio, or on your stereo with the broadcast presets to sound just like an FM broadcast station. These units are what keeps all the audio in check and clean on commercial stations. It sounds amazing when used for SSB. $1050 shipped.
Both located at my home in Fallon NV. Pick up discount for anyone Cross posted w more pics on QRZ; Listing #1751246 - Submitted on 11/30/25 by Callsign K5BLS - IP: syn-174-083-177-088.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
