nicFW900 V4.00.11
Added 2025-05-18 08:59:56 +0000 UTCIntroduces two new menus.
Menu 2 "Noise Floor"
-- Allows adjustment of the absolute highest noise level, above which the radio will always consider the channel as having no signal. This value was previously hard coded as 55 but is now adjustable. Default value is 55 in the SPI App. The menu option also displays a live reading of the noise level of the current VFO to aid in calibration of the setting. Should really be called "Noise Ceiling" but I've named it now.Menu 68 "Console Debug"
-- This option is not saved after power cycle. It is meant to be turned on when experiencing an issue such as the infamous "frequency shift" problem. It will then dump out over the serial port the entire BK4819 register list every 10 seconds. Using the "Monitor" tab on the API App in ASCII mode will allow you to see this.

No idea, you've told me virtually nothing about how your radio is configured. Did you follow the correct initialization process? I'm thinking probably not.

2025-05-19 05:48:31 +0000 UTCNicsure.. Finally I got the correct RT900 and I get to play with it. I was able to burn the firmware, but it won't transmit. I press PTT and nothing happens, it feels like the PTT button won't do anything. Also is not like it looks like it's transmitting and no power comes out, but it looks like "Nothing" happens... Any Idea?

2025-05-19 05:28:03 +0000 UTCI have a 900 arriving tomorrow morning so I will be able to help with this. Wanted to help give back a little for your great work on the h3.

2025-05-19 02:38:22 +0000 UTCThanks, I now am almost certain the BK4819 has somehow gotten into an unstable state.

2025-05-18 18:10:35 +0000 UTCHere are more dumps. Here is on 446.01250 https://pastebin.com/8rTv7TRj and on 145.05000 https://pastebin.com/sVXtYaUJ And some pictures with the power meter and the frequency count on it ( https://imgur.com/a/TGgO0he ) The drift is not that bad as before for some reason but still enough to not open the squelch on other radios even when outputting high power. The Xtal makes absolutely no difference i went from -200 to +200 and the frequency counter showed the same frequency as with value at 0. The Noise Floor in the drifting state varies from 60 to 80 and removing the antenna makes no difference but it makes a difference when i remove it in normal state it goes from 20 with antenna to 60+ without the antenna.

2025-05-18 15:32:33 +0000 UTCHere mine: OK https://pastebin.com/1STF9GsV Deaf https://pastebin.com/As34FuTb Deaf again: https://pastebin.com/WQGZNrxy Settings https://pastebin.com/SgHNd3JQ Radio was just scanning memories. It went back OK just after switching off/on.

2025-05-18 14:23:39 +0000 UTCWere you tuned to 126.8 MHz at the time of the dump? Also it would be interesting to see if there's any difference between the noise floor on an unused frequency when the radio is operating correctly, againt when it goes into the error state.

2025-05-18 12:49:55 +0000 UTCHere is my dump when the radio went in that state. https://pastebin.com/Biwdh1hw I only let in run for 20 seconds because i notices things started to repeat but i can let it run for much longer if necessary. Also, on a strong signal the noise floor was under 20 but on the same signal with the radio in that frequency shift state the noise floor was over 60 if this matters. (probably doesn't since there is no signal :) )

2025-05-18 11:53:50 +0000 UTCYes, please

2025-05-18 10:17:25 +0000 UTCI've been running with debug option enabled, I've just hit the problem of the radio going deaf, is the register debug going to be of use to you?

2025-05-18 09:59:37 +0000 UTCMine's all over the place, from 57 to 70

2025-05-18 09:55:44 +0000 UTCJust flashed it. Curious what noise floors most people are seeing, mine is reading about 62-64
