Any old-style Ten-Tec filter should be tested before purchasing - caveat emptor.// ===== Crystal Filter Comparison ===== ^ Model: ^ [[216]] ^ [[217]] ^ [[218]] ^ [[219]] ^ [[220]] ^ [[221]] ^ [[282]] ^ [[285]] ^ [[288]] ^ ? ^ ? ^ | Center Frequency | 9.002210 | 9.000750 | 9.001500 | 9.000750 | 9.001500 | 9.000500 | 6.299250 | 6.299250 | 6.300000 | 6.300000 | 6.300000 | | 6 dB BW, Hz | 500 | 500 | 1800 | 250 | 2400 | 250 | 250 | 500 | 1800 | 2400 | 6000 | | Shape Factor, 6/60 dB | 2.75:1 | 2:1 | 1.8:1 | 2.4:1 | 1.7:1 | 2.4:1 | 3.4:1 | 2.9:1 | 1.75:1 | | 1.87:1 | | Insertion Loss, dB | 8.0 | 7.5 | 2.0 | 10.0 | 2.2 | 10.0 | 11.5 | 5.5 | 2.5 | | | | Ultimate Rejection, dB | 90+ | 90+ | 90+ | 85+ | 90+ | 85+ | 90+ | 90+ | 100+ | | | | Z in & out, Ohms | 200 | 200 | 200 | 200 | 200 | 200 | 200 | 200 | 200 | | 200 | | Number of Poles | 6 | 8 | 8 | 6 | 8 | 6 | 6 | 6 | 8 | 8 | | | Stock Code | 48161 | 48036 | 48037 | 48055 | 48058 | 48243 | 48054 | 48053 | 48075 | 48074 | | ^ Current Model No.: ^ N/A ^ [[2017]] ^ [[2018]] ^ [[2019]] ^ N/A ^ N/A ^ [[2082]] ^ [[2085]] ^ [[2088]] ^ N/A ^ N/A ^ ===== Model Listing ===== ^ Model ^ Image ^ Description ^ | [[114]] | {{none.gif}} | Audio Filter for Argosy II | | [[208]] | {{208.jpg?100}} | CW Filter for the [[509]], 2 position, $29 New | | [[208A]] | {{208a.jpg?100}} | CW Filter with Notch for the [[515]], 3 position | | [[216]] | {{none.gif}} | 500 Hz 6 Pole FSK Filter, 9 MHz | | [[217]] | {{217.jpg?100}} | 500 Hz 8 Pole Ladder Filter, 9 MHz | | [[218]] | {{218.jpg?100}} | 1.8 KHz 8 Pole Ladder Filter, 9 MHz | | [[219]] | {{219.jpg?100}} | 250 Hz 6 Pole Ladder Filter, 9 MHz | | [[220]] | {{220.jpg?100}} | 2.4 KHz 8 Pole Ladder Filter, 9 MHz //(first used in the Corsair - Omni series used a 2400hz 8-pole filter with a different form factor)//| | [[221]] | {{none.gif}} | 250 Hz 6 Pole Ladder Filter, 9 MHz, Passband centered at 500 Hz | | [[224]] | {{none.gif}} | Audio CW Filter for Argosy | | [[235]] | {{none.gif}} | CW Filter for Model [[315]] Receiver, $14.95 New | | [[245]] | {{245.jpg?100}} | CW Audio Filter Board | | [[282]] | {{282.jpg?100}} | 250 Hz 6 Pole Ladder Filter, 6.3 MHz | | [[285]] | {{285.jpg?100}} | 500 Hz 6 Pole Ladder Filter, 6.3 MHz | | [[288]] | {{288.jpg?100}} | 1.8 KHz 8 Pole Ladder Filter, 6.3 MHz | | [[2000]] | {{:2000.jpg?100|}} | 1.8 kHz roofing filter, 9 MHz I-F, for Orion II Model [[566]] Only | | [[2001]] | {{:2001.jpg?100|}} | 600 Hz roofing filter, 9 MHz I-F, for Orion II Model [[566]] Only | | [[2002]] | {{:2002.jpg?100|}} | 300 Hz roofing filter, 9 MHz I-F, for Orion II Model [[566]] Only | | [[2017]] | {{217.jpg?100}} | 500 Hz CW filter, 9 MHz I-F, direct drop-in replacement for Model [[217]] | | [[2018]] | {{218.jpg?100}} | 1.8 KHz SSB filter, 9 MHz I-F, direct drop-in replacement for Model [[218]] | | [[2019]] | {{219.jpg?100}} | 250 Hz CW filter, 9 MHz I-F, direct drop-in replacement for Model [[219]] | | [[2031]] | {{2031.jpg?100|}} | 500 Hz Collins Mechanical filter, 455 kHz I-F, for Omni VII Model [[588]] | | [[2032]] | {{2032.jpg?100|}} | 300 Hz Collins Mechanical filter, 455 kHz I-F, for Omni VII Model [[588]] | | [[2082]] | {{282.jpg?100}} | 250 Hz CW filter, 6.3 MHz I-F, direct drop-in replacement for Model [[282]] | | [[2085]] | {{285.jpg?100}} | 500 Hz CW filter, 6.3 MHz I-F, direct drop-in replacement for Model [[285]] | | [[2088]] | {{288.jpg?100}} | 1.8 KHz SSB filter, 6.3 MHz I-F, direct drop-in replacement for Model [[288]] | | [[2203]] | {{none.gif}} | Highpass Filter, -3dB @ 1.1 MHz for Orion tx used with Acom amplifier | | [[5060]] | {{5060.jpg?100}} | High Pass Filter | | [[5061]] | {{5061.jpg?100}} |Low Pass Filter, 2 KW | | [[48034]] | {{omni_filter.jpg?100}} |2.4Khz 8-pole filter, 9 MHz for Omni series | | [[FR4]] | {{fr-4.jpg?100}} | Audio Filter, 400 Hz |
