nicFW880 BETA 04E Update
APRS Is in EARLY STAGE.This means it's not going to perform like other radios' APRS systems ... YET!!!It takes time to get all of this right and these releases are incremental as features are added,meant primarily for testing before moving onto the next phase. So don't post complaining t...
RT-880 nicFW's First "Real" APRS Packet
Yet to be tested before release.
RT-880 Proof of Concept Audio Injection
This is EXTREMELY rough and still in the very early stages, but the sound is audible and functional (although there is a weird buzzing which I will need to address)Here’s how it works: when transmitting, press SP1 (the middle side button), and the regular voice prompt audio samples will be injecte...

Radio Frequency Calibration for nicFW
Choose a frequency to calibrate on, the higher the betterExample: 433 MHz(It's usually best to pick a dead on MHz value to keep the maths simple)Tune both radios to the same frequency using VFO modeOn the radio to tune, set a RX squelch tone and set the step to 0.1On the transmitting radio set t...
RT-880 Testing GPS [Phase 2]
Better
RT-880 Testing GPS [Phase 1]
Not a great start, since we lack TX to the GPS chip we can't change its settings to give a longer sample length for the heading calculation, so we'll have to extract it using coordinates over time.
RT-880 DTMF Decoding Primer [Radio Side]
Yes, I did notice the ghost '4' character on the clock readout. It's a remnant from the dBm readout being 1 character longer.

Compilation of Release Notes for nicFW 880 ALPHA Releases
Thanks to Mike Ward for putting this together for us.https://github.com/nicsure/FontConvert880/blob/e76b6fbf82c3957f98885eea174892801ec2dc43/nicFW880_ALPHA_Release_Notes.pdf
nicFW 880 BETA 01 Release
IMPORTANT:I have a Radtel RT-880, a Radtel RT-880G and an iRadio UV-98 Plus, all of which have serial numbers greater than 300 (i.e. current models). These are the ONLY radios I can support. Radtel assure me that the sub 300 serial number units differ only by the firmware flashing process so these R...

Reporting Issues
There needs to be some standard about how bug/glitch reports are made because nicFW is very complex and when people report bugs they always miss vital information.Every bug report should state that this post has been read and understood.The most important thing in any report is NOT describing the fa...
Advanced Menu Overview (RT 880)
SPI DeferralThis setting defines the delay, in seconds, that the radio waits after a user action before saving changes to flash memory. Delaying writes helps extend the life of the flash storage.Warning Indicator: While changes are pending, a red warning triangle appears on the display.Important: Do...
nicFW 880 ALPHA 18a
!! This firmware DOES NOT SUPPORT The iRadio UV-98 (Plus) !!The iRadio UV98 (Plus) is NOT THE SAME as the Radtel RT-880(G), there are differences.At the current time I do not have a UV-98 so it's impossible for me to support the model. I have one on order, but until then no support for the iRadi...
Squelch Settings Overview (RT-880)
Noise CeilingDescription:The Noise Ceiling sets the threshold at which external noise (ex-noise) is considered maximal. When the noise level reaches this point or above, the squelch will close immediately, without delay or exception.Effect:Any noise at or above this level triggers instant squelch cl...
Combining RT-880 Antennas
In order to try to get the scope working in the Si4732 Tuner HF bands, this is the contraption I came up with. It works but... it scares the cheese out of me. I'm pretty sure if I were to accidentally transmit while this monstrosity is wired up, it would fry the Si4732 to death. So, not somethin...
nicFW880 ALPHA 17
!!The firmware DOES NOT support sub 300 serial number radios!!IMPORTANT:You must follow the SPI Flash restore process [Here]USB and LSB modes in the Si4732 Tuner will not operate correctly if you don't.After you have restored the SPI Flash, close the RMS and reopen it.Hey everyone!Here is the AL...
nicFW880 Flash Restore Process
Before the release of ALPHA 17, just a heads up on what will be required.This process is essentially a "Restore to Factory Settings", so it's useful in other ways too. Kind of like an EEPROM_WIPE for the H3 before putting the stock firmware back.
nicFW880 ALPHA 16
!!The firmware DOES NOT support sub 300 serial number radios!!The big highlight of this release is the new Si4732-based FM Tuner! 🎶 It’s still early days, so for now it only covers the FM broadcast banThe big highlight of this release is the new Si4732-based FM Tuner! 🎶It’s still early day...
