ALTERNATE VERSION
This version uses an alternate mode for the soft AGC. It uses minimum peaks (vs rms) for the gain calculations over a period of symbols. This is similar to the AGC fw on the P25RX. This has been reported to work better than the rms-calculations for some. This version will reset the configuration. Other changes to the defaults include LNA = fixed 20dB gain, VGA target of 60dB, and VGA step time of 10ms.
BTConfig-2021-10-31_1523 (Latest Testing P25RX)
LATEST RELEASE 01-29_1944 - This version will ship with new receivers.
Fix minor bug. 01-29_1914
Revert back to different phase error calculation and EVM calculation. 01-29_1858.
Increase order of the channel filter. 01-29_1330
Fix bug that was causing a DMR frequency to be used on power-up when in P25 mode. Disable "find min vga gain" button for now. Use AUTO mode. 01-29_0634.
Remove unneeded options from advanced tab. 01-29_0446
Fix EVM calculations. for P25 P1/P2. 01-29_0411
Optimization of channel filter bandwidths. 01-28_1242
Huge improvement to the DSP code!!!! 01-28_1129
Fix EVM calc issue
Fix drawing issue on signal insights tab.
Add more zones. (total of 12)
Improvements to demod
PREVIOIUS RELEASE 01-24_1017
This version will ship with new receivers. This may be the last version before scanning profiles are added to the firmware / software. If you are monitoring a simulcast system, then try selecting the LSM-simulcast demod option and enable the equalizer for the best performance.
Remove debug code that was enabled with the TG hold button. 01-24_1017
Significant improvement to the LSM demodulator resulting in imrproved EVM. 01-24_0649.
Re-initialize equalizer coefficients on a frequency change. 01-23_2339
Channel equalizer now works in both modulation modes. VGA gain now defaults to AUTO. The VGA Calibration has been renamed to "Find Min VGA Gain". It is usually better to set the VGA gain to AUTO. If you do set it to manual, then don't set it any less the the reported minimum. In fact, set it 6 dB higher unless you are dealing with very hot signals and want manual control. Fixed issue where P25 P2 was always reporting LSM for the demod. 01-23_1837.
Change to the parameters that lock-in equalizer trained coefficients. 01-23_1434
Equalizer training period after a frequency change is 4800 symbols with a good EVM. 01-23_1233.
Added a LMS (least-mean squares) channel equalizer for the LSM (linear simulcast modulation) demod mode. ( tighter symbol clusters, better EVM). 01-23_1003.
Fix bug causing TG LED to get stuck on in some cases. 01-23_0825
Minor change to EVM display in CQPSK/P2 mode. 01-23_0613
Faster EVM updates. P2 verified to work in LSM and CQPSK modes. 01-23_0051.
Fixed $P25_MODE$ display when on CC. Changed LSM demod. 01-22_2211.
The terminology for the demodulators has changed to avoid confusion. The options are now: LSM Simulcast (was previously labeled CQPSK), and CQPSK/C4FM
There are new channel filter options. AUTO will select 8.1 kHz for CQPSK and 8.7 kHz for LSM-Simulcast.
Added "enable voice frame repeat" option on the advanced page. This will reuse voice frame coefficents on voice frames with too many errors. It may help keep the voice from being choppy, but may also introduce weird noises if there are lots of errors. If you disable this, then voice frames with too many errors will be replaced with silence.
The default AGC target level is now -10 dB, RF Hysteresis is 6 dB.
LATEST RELEASE
Note: After Updating To To The Latest Version With TG Zone Support:
1) select all TG rows in the talk group editor. 2) Press the <Set Selected Zones> button. 3) Enter 1 for the zone. 4) Press the <Write Talk Groups> button. 5) Make sure the '1' button for the Zones is green. (press if not).
You can select what Zones will be enabled on power-cycle or a read of the configuration from the P25RX device. On the talk group editor tab, there are check-boxes for the zones. Setting these and writing the configuration will determine the default enabled zones on power up.
Remove quck-frequency-buttons until after scanner support is added. 01-09_0946.
Don't force currently selected frequency button to be the current frequency. This was causing issues with conventional mode. The frequency buttons only change frequency when pressed. They are equivalent to the 'freq xxx.xxxxx' command. 01-09_0926

Fix new issue with logging RIDs on P2 system. 01-06_0949
Revert change to emulate 11-24 version. Effectively back to 01-04_1131 (with a couple of fixes). 01-04_1359.
More changes to emulate the configuration of version 2021-11-24 by default. This will reset the configuration. 01-04_1300.
