TYT Companion Disk

TYT Companion Disk


I’ve put together a disk of files for the TYT range.. to help I’ve included a simple web page which will navigate around the directories under radio headed titles..


Enjoy… feel free to share codeplugs etc so I can help others, if you improve mine that’s fine, but please ping me over a copy 🙂


As I write this we are updating the new northern repeater line up on Brandmeister, we have worked hard to make sure the Phoenix is working on both the 2017/RT82 as well as the new MD9600…


Again your help, comments etc are always welcome! the disk zip can be found here: DMR Companion.

MD 9600, RT90, RT82, MD 2017

MD 9600, RT90, RT82, MD 2017

So the MD9600 has been modified, the clicking has been reduced (not completely) but this is a very cheap little radio, and to be honest you get a lot for your money, so I’ll forgive a few small .. OK you will have to be creative with the Codeplug to get over the strange VFO, again this is just part of the quirky nature of the Chinese radio culture. The Retevis RT90 is the same radio re-badge’d hopefully this has had the mods done as I’ve not had one on test.

The MD2017 has been popular, though I am hopeful that TYT address the antenna mount issues that have plagued it, I have not seen the same issues on the RT82.. the great news on all of these radios is that modified firmware keeps coming along allowing for ever more advanced uses of these little handhelds..

I’m just creating a future video list of all these radios and many more! if you have specific questions PLEASE just comment I will get back to you 🙂


I’m back after trapping a nerve in my shoulder, Dohhhh

I’m back after trapping a nerve in my shoulder, Dohhhh


who says exercise is good for you? I managed to trap a nerve in my shoulder meaning I’ve not been drawing or playing with electronics for a few weeks. not good, I’ve not uploaded any videos but do have a couple in mind for the very near future..

I’ve had a few questions via YouTube  and I hope I managed to answer them all, and as always please let me know if there is a particular radio etc you want me to look at.. I’m about to revisit the MD-9600 and RT90, 2 of the cheap DMR radios that hit the market a few months ago.. I have seen the updated model with improved function more detail in a follow up post..

I had a couple of folk ask me about drawing and painting, I’m not sure I’m qualified really to advise, however it was pointed out inspiration needs no qualification, I agree and will see what I can do.. 🙂


HAK5 Packet Squirrels have landed at work!!!!

Oohh its nice! the Icom ICR-8600

Oohh its nice! the Icom ICR-8600

Whether deployed with two receivers on a single 19-inch rack, or on your desk at home, the IC-R8600 is an impressive upgrade to any serious SIGINT team, interference research team, or the avid shortwave or receiver enthusiasts. Covering 10 kHz to 3 GHz, this communication receiver enables you to hear and see a wide variety of signals on a 4.3-inch color display. Additionally, the R8600 decodes diverse digital communication signals, while the advanced FPGA processing technology provides clarity and accuracy of received signals. With the optional remote control software for a Windows® PC, received audio and spectrum scope data can be transferred through an IP network for monitoring from remote locations.

RX frequencies:

10kHz – 3GHz
Decodes digital including P25, NXDN™, D-STAR
RX analog including USB, LSB, FSK, CW, AM, S-AM, FM & WFM


2000 with 100 groups
100 scan skip channels
50 pairs scan edges


Cellular frequencies blocked or unblocked

Receiver performance

The R8600 has 11 discrete RF bandpass filters in the HF bands and 13 bandpass filters in the VHF/UHF bands. To prevent overflow, only the intended signal is passed, while it rejects any out of range strong interference signals. The R8600 provides +30dBm IP3 and 105 dB dynamic range at 14.1MHz. IP3 performance is +10dBm at 144 MHz and 0dBm at 440MHz.

Software demodulation in FPGA processing

The R8600 utilizes FPGA (Field Programmable Gate Array) and DSP units for demodulation, decoding and most signal processing. Direct HF signals and intermediate frequency signals, which are converted from VHF/UHF signals, are digitized in a 14-bit A/D converter and transferred to the FPGA and DSP for optimal processing. The high-rate 122.88 MHz sampling frequency used for the A/D converter results in superior aliasing and image reception reduction.

Software Demodulation in FPGA Processing

Real-time spectrum scope

An industry first for desktop wideband receivers, the IC-R8600 has a high-resolution real-time spectrum scope with a waterfall screen. The display offers first class performance in resolution, maximum 30 frames per second fast sweep speed, ±2.5 MHz wide scope span (display range) and 110dB of dynamic range (at ±2.5 kHz span). The waterfall screen allows you to find weak signals by showing the spectrum change over time. Tap the spectrum scope or waterfall screen to select as the operating frequency. The peak search function finds several peak frequencies within the scope range, and helps you to select these.

The spectrum scope offers the simultaneous operations found in some of the more expensive rigs! This means you can use either the spectrum scope or the waterfall to quickly move to an intended signal while listening to the receiver audio. The ‘R8600’s touch screen introduces a “Magnify” function. When you first touch the scope screen around the intended signal, the touched part is magnified. A second touch of the scope screen changes the operating frequency and allows you to accurately tune.

Intuitive operation

To efficiently acquire intended signals, the IC-R8600 user interface provides quick and accurate operation. The large 4.3-inch color display, with touch screen function, is configured to collect operating information. By tapping indications and icons on the screen, the setting menu will pop up and parameters can easily be adjusted. Push either the DIAL A, B or C multi-function control knobs to display various functions such as, scan speed, RF gain, audio tone, display backlight and more.

Pop up menu appears by pushing DIAL B

RSSI (Received Single Strength Indicator)

The IC-R8600 shows S-meter, dBµ¬, dBµ¬ (emf) and dBm meter types in the RSSI. The dBµ¬, dBµ¬ (emf) and dBm meter has a high ±3 dBµ accuracy (between 0.5–1100 MHz) that can be used for measuring signal strength level.

Additional features

  • SD card slot for received log, decode log and voice recording
  • Screen capture function saves a screen shot in PNG or BMP format
  • I/Q signal output for use with future firmware upgrade and third-party SDR software and/or external decoding
