SSB Electronic Masthead Super Amp 70cm: SSB Electronic Super Amp SP70
This is the best of the best masthead preamps for 70cm band, made in Germany. A must for LEO satellite work, 70cm contesting, 70cm weak signal or EME. They go for about $500 new, and prices are going up significantly due to import tarrifs. This one is in excellent condition and everything works as it should.
Just $325 shipped CONUS.
The SP 70 is a selective receive preamplifier for the 70 cm amateur radio band with transmit / receive switching. It offers adjustable gain, low noise and good large-signal response. Adding cable and plug losses to the noise figure of the transceiver will surprise you with how fast 8 dB or more of the total system noise can be achieved. The use of this preamplifier makes this calculation unnecessary. The overall noise level of the receiving system is abruptly reduced to about 1 dB when using this preamplifier. Up to 22db gain.; Listing #1745730 - Submitted on 10/09/25 by Callsign K1FIE - IP: syn-016-203-133-064.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
