ATS-20 new Firmware test
AM SW Scan +- included ..
To reduce noise, interference and interference from the Arduino Nano board, the following new features have been added:
for FM, completely turn off RDS with the MODE button;
for all ranges, turn off the S Meter with the VOL- button;
and the most cardinal method, which removes almost all interference and interference - turning off the display and deep sleep mode of the Arduino Nano board with the BAND- button (exiting sleep with the encoder).
Completely redesigned interface, large fonts, easy to read.
2. Radio text is displayed in a separate window with the Mode button (last slide).
3. Added brightness adjustment, when brightness = 0, the receiver goes into deep sleep. Now the receiver is comfortable to use in the dark, it does not blind (on all slides, except for one [103.6 FM], the lowest brightness is set).
4. Minor fixes in terms of remembering settings.
Added the ability to turn on forcibly sound in mono for VHF. The mono mode is activated with the Vol- button, alternately with the S-meter. Indication for forced mono: F.Mono
Improved work in SSB mode. Now BFO does not go to infinity, but is regulated within -1000/+1000 Hz in 50/5 steps. When the limit is reached, the receive frequency changes by -1 / +1 kHz, respectively. Also, the S-meter and attenuator are disabled for SSB, since the former is not informative, and the latter did not work at all.
Added memorizing the position of the AGC switch (on / off) and attenuator values separately for VHF and AM bands. For SSB, only the AGC is remembered.
how this firmware for ATS-20 differs from others:
• Soft Mute is disabled (the sound is no longer muted when the frequency is not accurately tuned or the signal is very weak) for all bands, including FM.
• Disabled Blend Stereo for FM (ie now the stereo in the headphones is always as full as possible, regardless of the signal strength, unless, of course, the signal has stereo).
• A large number of settings with their entry into non-volatile memory, including display brightness.
• Display full RDS radio text (all 64 characters) for FM.
• The ability to turn off the indication of signal strength and RDS, as well as a deep sleep mode with display off - to reduce the effect of various pickups when receiving weak signals, especially on FM.
Another small recent update regarding auto-search for FM: the auto-search step now changes according to the manual seek step set by the Step button (it was always auto-search in 10 kHz steps). For AM bands, setting the auto-search step was implemented earlier (maximum step 10 kHz).
For AM bands, a synchronous detection mode has been added, it is
turned on by the Mode button in series with SSB,
indication: SYNC
