The filter is designed with a No-Synch (NOS) design, which means it does not require any external synchronization to function properly. This makes it a convenient choice for use in portable or handheld radio systems where external synchronization may not be available.
The Collins Mechanical Filter 526-8610-020 is constructed with high-quality materials and components, ensuring that it is built to last. Its compact size and rugged design make it easy to integrate into a variety of radio communication systems, making it a versatile choice for a wide range of applications.
In summary, the Collins Mechanical Filter 526-8610-020 is a high-performance, narrowband filter designed for use in radio communication systems. Its symmetrical CW response, No-Synch design, and durable construction make it a reliable and convenient choice for a wide range of applications.
Pros of the Collins Mechanical Filter 526-8610-020:1. High Quality: Collins is a well-known brand in the radio communication industry, known for its high-quality products. This filter is no exception.
2. Frequency Range: The filter is designed for 455 kHz, which is a common frequency for many radio communication applications.
3. Bandwidth: The filter has a bandwidth of 500 Hz, which is suitable for narrowband applications, ensuring minimal interference.
4. Symmetrical CW: The filter is designed for continuous wave (CW) operation, which is beneficial for radio communication where only one frequency is being transmitted at a time.
Cons of the Collins Mechanical Filter 526-8610-020:1. Price: Collins products are generally more expensive than other brands due to their high-quality standards. This filter is no exception and may be beyond the budget of some users.
2. Size and Weight: Mechanical filters can be larger and heavier than electronic filters, which may limit their use in portable applications.
3. Maintenance: Mechanical filters require more maintenance than electronic filters, as they can get clogged or damaged over time.
Conclusion:The Collins Mechanical Filter 526-8610-020 is a high-quality filter suitable for narrowband applications at 455 kHz. Its symmetrical CW design makes it ideal for continuous wave radio communication. However, its high price, size, and weight may limit its use for some users, and its maintenance requirements should be considered.
Recommendation:If you require a high-quality filter for a narrowband application at 455 kHz and can afford the higher price, then the Collins Mechanical Filter 526-8610-020 is a recommended option. If, however, price, size, and weight are concerns, you may want to consider alternative electronic filters that may offer similar performance at a lower cost and with less maintenance requirements.
I have on this listing 500 hz narrow band width for cw filters. These are the new flat torsional type mechanical filters not old disk wire loaf of bread made by Rockwell-collins, same great specs, more modern design. These are all 455 khz frequency and symmetrical cw filters. You are buying one filter at a time.
The model numbers are for 500 hz. These are all new old stock from Watkins Johnson and were used in receivers like the wk-87 etc.
