P275 FM Analyzer / Re: Histogram data from serial connection

« Last post by Jan on December 27, 2025, 10:12:57 am »

It consists of pairs

bin; count

for each deviation in range 0 to 121 kHz.

Value separator is space or CRLF in any mixture and quantity.
The separators are corrupted in recent firmware version. It makes no issues for processing but does not look well. This will be fixed in fw version 2.2f.

P275 FM Analyzer / Histogram data from serial connection

« Last post by genunix on December 27, 2025, 09:51:22 am »

Hi. I have a question regarding the interpretation of histogram data obtained from a serial port using the ?H command.
Here is the data:

"Histogram Data:",
"0; 0 1;",
"0 2;"
...
"0 120;",
"0 121;",
"0"

What does the first value in the first row (0; 0 1;) mean?
What does the value in the last row (0) mean?"

Please follow the manual for complete list of power supply options. The supply voltage you suggested is not directly supported by the board.

P275 FM Analyzer / Re: signal quality

« Last post by Jan on December 08, 2025, 08:27:35 pm »

The signal level has no bearing on the reception quality required for modulation measurements, except that at low levels the conditions are unlikely to be met.

The reception quality indicator entirely ignores the signal level. Please refer to the pdf manual for more information about what parameters and influences are monitored to determine the quality of reception. To improve the reception, especially in areas with many signals from several directions, use an antenna with directional effect and correct polarization. Also pay attention to the section discussing HD Radio (if applicable).

Control Software / Re: Magic RDS 4 Won't Connect

« Last post by Jan on December 05, 2025, 11:34:38 pm »

Thanks for providing all information. There's no issue of such kind in the Magic RDS 4 or in the devices. You've checked several units and several PC machines so individual failure can be ruled out and the problem is solely related to the setup procedure. In that case, I have to refer you to the device PDF manual, where the setup procedure is described in detail. There's nothing special, just basic rules. If you are not experienced with operating Ethernet devices, get someone who knows the basics.

In particular, make sure that if one side is set as a TCP server, the other side is a TCP client, and vice versa. You don't need to deal with the RDS Spy connection at all, the RDS Spy is a part of the Magic RDS 4 package and, when the connection is working, it is accessible with one button without the need for any additional configuration.

Typically the time required for the setup in local network is ~2 minutes.

Please provide screenshots: TCP setup in the ConfigTool, Connection Overview in the Magic RDS 4 and DHCP configuration in your network router.

Control Software / Magic RDS 4 Won't Connect

« Last post by rogertee1966@gmail.com on December 05, 2025, 11:29:03 pm »

We are in the process of configuring the P164 units. We have 4. All 4 exhibit the same issue. Configuration was going fine and suddenly just quit connecting. We have tried direct connection, 4 different machines, 3 OS's (Win 7, 10 & 11) and even attempted going back to Magic RDS 3. We can see the box through the web interface i.e. web browser to IP address, without issue. The RUNDONFIG tool in the Magic RDS software seems to connect but neither the control software nor the RDS Spy connect. We have checked, double-checked,triple-checked IP and port settings without success. Any idea of what we might be missing?
