The BCD325P2 does not receive Phase 2 digital signals

The Uniden BCD325P2 is a handheld scanner that picks up conventional analog radio frequencies and some digital modes, but it cannot decode Phase 2 trunked systems. Phase 2 is a specific digital trunking standard used by some police, fire, and emergency services across the United States. If your local agencies broadcast on Phase 2, this scanner will not receive those transmissions — it will either hear nothing or hear only noise.

The BCD325P2 can receive Phase 1 trunked systems, which is an older digital trunking format. It also receives conventional FM frequencies in the VHF and UHF bands, plus some digital modes like DMR and NXDN. But Phase 2 specifically requires hardware and firmware that this model does not have.

Key Takeaways

  • The BCD325P2 receives Phase 1 trunked systems but cannot decode Phase 2, which is used by some police and fire departments.
  • You can check what trunking standard your local agencies use by visiting RadioReference.com and searching your county or city.
  • If your area uses Phase 2, you would need a different scanner model, such as the Uniden BCD436HP or BCD536HP.
  • The BCD325P2 still receives all conventional analog frequencies in the VHF and UHF bands, even if Phase 2 is unavailable in your area.

How to find out what your local agencies broadcast on

RadioReference.com is the most reliable source for finding out which trunking standard your local police, fire, and emergency services use. Go to the site, search for your county or city, and look at the frequency listings. The entry for each agency will say whether it uses Phase 1, Phase 2, or conventional (non-trunked) frequencies.

You can also contact your local police or fire department's non-emergency line and ask directly. Many dispatchers are willing to tell you what system they use, especially if you explain you are interested in monitoring for emergency information.

Which Uniden scanners do receive Phase 2

If you need Phase 2 capability, Uniden makes several models that support it. The BCD436HP and BCD536HP are both handheld and mobile scanners that decode Phase 2 trunked systems. The BCD536HP is larger and designed for vehicle installation, while the BCD436HP is portable like the BCD325P2.

Both of these models are more expensive than the BCD325P2 and have larger screens and longer battery life. They also receive Phase 1, conventional FM, DMR, NXDN, and other digital modes. If Phase 2 is the only thing your BCD325P2 cannot receive and you need it, upgrading to one of these models is the standard solution.

What Phase 1 trunking means for your BCD325P2

Phase 1 is an older digital trunking format that the BCD325P2 handles without any problem. Many smaller cities and rural areas still use Phase 1 systems, and some larger agencies run both Phase 1 and Phase 2 systems in different parts of their coverage area. If your local agencies use Phase 1, your scanner will track and decode those transmissions automatically once you program the system frequencies.

The main difference between Phase 1 and Phase 2 is how the system allocates radio channels and how the scanner tracks which channel an active conversation is on. Phase 2 is more efficient and allows more users on the same system, which is why newer and larger agencies have switched to it. But for listening purposes, Phase 1 works just as well on compatible hardware.

Conventional frequencies still work even if Phase 2 is not available

Many agencies broadcast on both trunked systems and conventional frequencies. Even if your area uses Phase 2 and your BCD325P2 cannot receive it, you can still monitor the agency's conventional frequencies. Police departments often use conventional channels for routine traffic stops, welfare checks, and other non-emergency calls, so you will still hear a significant amount of activity.

Check RadioReference.com for your area's conventional frequencies. You can program these directly into your scanner without any special setup. This is often a practical workaround if Phase 2 coverage is limited in your region.

Programming and firmware limitations

The BCD325P2's inability to receive Phase 2 is a hardware limitation, not a software one. Uniden cannot add Phase 2 support through a firmware update because the scanner lacks the necessary radio chipset and decoding circuits. This is different from some features that Uniden has added to scanners through software updates over the years.

If you already own a BCD325P2, you can keep it updated with the latest firmware from Uniden's website, but this will not unlock Phase 2 reception. Firmware updates typically add new digital modes, improve stability, or expand frequency support, but they cannot change the fundamental hardware capabilities.

Frequently Asked Questions

Can I use a software update to make my BCD325P2 receive Phase 2?

No. Phase 2 support requires specific radio hardware that the BCD325P2 does not have. Firmware updates cannot add this capability. You would need to purchase a different scanner model.

Will my BCD325P2 make noise or stay silent if Phase 2 is broadcast in my area?

It will stay silent or produce static. The scanner cannot lock onto Phase 2 signals, so it will not decode them. You will hear nothing useful, though you may hear brief bursts of noise as the system transmits.

How do I know if my local police use Phase 1 or Phase 2?

Search your county or city on RadioReference.com and look at the police frequency listings. The entry will specify which trunking standard is used. You can also call your local police non-emergency line and ask.

If I buy a Phase 2 capable scanner, will it still receive Phase 1?

Yes. Scanners like the BCD436HP and BCD536HP receive both Phase 1 and Phase 2, plus conventional frequencies and other digital modes. They are backward compatible.

Can I listen to Phase 2 systems online instead of buying a new scanner?

Yes. Websites like RadioGarden and Broadcastify stream live audio from many police and fire departments, including those on Phase 2 systems. This is a free option if you only want to listen occasionally.
