Hallicrafters S-9 vs SX-9 differences?
I have a "Super Skyrider" which I believe is either an S-9 or SX-9 but
I have been unable to determine what the difference is between the two model numbers or which one I have. Can you help? Thanks! 73 Carl WS7L |

Thanks! 73 Carl WS7L SX receivers incorporated a simple 455kHz crystal filter (like the Lamb circuit) with the phasing, etc. controls for setting the bandwidth. Pete |

Thanks! 73 Carl WS7L Just plug a 455khz xtal in the socket on the deck and you'll have a SX-9 BH |

Thanks! 73 Carl WS7L Just plug a 455khz xtal in the socket on the deck and you'll have a SX-9 BH It may not be that easy. While some rx were built so that a crystal filter could be added it was usually in the form of a kit or assembled filter with suitable punch outs on the panel and chassis. The early Hammarlund Super-Pro was like this, one could order a crystal filter _assembly_ to retrofit a receiver without one. Also, the IF frequency of the S-9/SX-9 was 465 Khz, a common IF frequency at the time. Until about the mid 1940's there really was no standardization of IF frequencies, common ones were 455khz, 456khz, 462khz, 465khz, 172khz (the last mostly in automobile receivers), and some others. -- --- Richard Knoppow Los Angeles, CA, USA |
