Here is nice Swan 500C 80-10 mtr.am/cw/ssb transceiver. Power output up to 250 watts.Recently realigned & works great.Requires the external 117-XC power supply/speaker which is listed seperately.Manual included. Introduced in 1967 as a deluxe version of the 350, the 500 offered 480 watts PEP-SSB power. The 500C, which was first sold in 1968, offered the same power output but had a 2.7 Kc bandpass for both transmit and receive, 50 db sideband suppression, and grid block CW keying. Pictured here is a deluxe version of the 500C, the SS16, complete with the 16 pole crystal filter. The 500CX was the final version of this series, and it offered the following improvements in 1970. New AGC circuit with faster attack and controlled decay, amplified automatic gain control (AAGC), 25 kc and 100 kc crystal calibrator, carrier suppression exceeding 60db, improved product detector, and increased AF gain with less distortion. A review of the 500C appears in the April 1969 issue of CQ. * Single Sideband, Suppressed Carrier: 520 watts PEP, minimum all bands * AM: (single sideband with carrier) * Distortion products down more than 30db * Unwanted sideband down more than 50db * Carrier suppression greater than 60db * Less than 0.5 microvolt at 50 ohms impedance for signal-plus-noise to noise ratio of 10db * Wide range Pi-network output matches antennas essencially resistive from 15 to 500 ohms impedance, with coarse and fine load adjustment. * V6 12BZ6 receiver rf amplifier * V9 12BA6 second IF amplifier * V10 12AX7 product detector / receive audio * V11 6BN8 AGC amplifier / rectifier * V15 12AX7 mic. amplifier / transmit audio * V17 12BA6 100kc crystal calibrator * Filiments: 12.6 volts, 5.5 amps, ac or dc * Medium voltage: 275 volts dc, 150 ma * High voltage: 800 volts dc, 550 ma. peak transmit * Recommended supplys: 14-117 12 volt dc supply, 117X basic ac supply, 117XC matching ac supply / speaker, 14-C dc converter (for 117-X). * 5.5 inches high by 13 inches wide by 11 inches deep (please look at our rules and privacy policy) |
