AN vs BN Radios
Several radios in the Astro25 line are considered "AN" or "4-meg" radios and contain a smaller flash rom chip (4 megabyte vs 8 megabyte) and are more limited in firmware and feature support. Earlier models of the XTS2500 and the Astro Spectra Plus are considered AN radios and are limited to the firmware version specified below.
Firmware
The latest firmware (as of 12/21/2016) is R20.50.08 for 8-meg BN radios and R09.00.41 for 4-meg AN radios.
Audio Enhancements
Analog and digital audio is processed by the audio DSP before it is sent through the RF section and transmitted. The default settings are fine, and most people will have no complaints with the quality of audio from these radios. However, as found through testing and tweaking by members of communications.support, there exists a much better setting for Astro25 radios that can make the transmitted audio from these units sound even better. These audio settings can be found in the Radio Configuration -> Radio-Wide -> Tx Audio Control Per Mode section of CPS.
The settings are as follows:
- Internal Mic: All AGC Checked
- External Mic: All AGC Checked
- AGC
- Output: -3
- Total: 12
- Noise Suppression: Checked
- Attenuation Level: Advanced
Software
Astro25 radios program using the Astro25 Portable and Mobile CPS Packages. The portable version of CPS supports the XTS2500, XTS4000, and XTS5000. Astro25 Mobile CPS supports the Astro Spectra Plus, XTL1500, XTL2500, and XTL5000.
Amateur Use & Bandsplits
If you have a radio whose bandsplit is outside the amateur bands (a UHF-R2 "S"-split radio for the 450-520 MHz band would be an example) you must modify the CPS executable to allow the software to accept frequencies which are out of band for the model. This is done using the Hex-edit Method which works for many CPS distributions, and detailed information can be found on the information page.
All Astro25 radios excluding the Astro Spectra Plus will tune to all frequencies in the amateur bands without issues. The Astro Spectra Plus VCO will not lock on some frequencies far from its rated band and requires a hardware mod to allow it to lock properly at these frequencies.
15+1 Trunking Scan
The offset for A25 Portable CPS R20.01 (and R20.00 as well) is 0x009301A1 and the change is from 0A to 0F (10 to 16 in decimal). The offset for Mobile CPS R20.01 (and R20, etc) is 0x009E4D51 and the change is once again from 0A to 0F.
