http://www.networksciences.com/45mhzmono.html WebA Bandpass Filter (BPF) is a 2-port Radio Frequency (RF) filter component which is used in a RF signal path to pass a specific range of frequencies and to suppress (attenuate) the frequencies on either side outside of that range. The most demanding BPFs are used in the RF front-end of Time Division Duplexed (TDD) systems at the antenna port. incarnation catholic church nashvillehttp://www.w7ekb.com/glowbugs/ModsEtc/modifications.htm inclusion\\u0027s zd

"WebThe MP, Mark V and Field have a 70.455 MHz crystal filter with a bandwidth of 12 kHz. The SFDR for signals outside this filter bandwidth is determined by the signal strength capabilities of the first mixer and RF stages. The INRAD mod is inserted after this filter and just prior to the second mixer. The mod gain is adjusted to 8 +/- 0.5 dB " - Crystal am filters
