Got Packet Loss?

Well I'm pretty sure it's time to get a new router!

There shouldn't be any red in this picture!

Radioddity GD-73A

The GD-73A (TYT MD-430) is a low powered dual timeslot UHF DMR/FM radio that's recently been released for the amateur radio use.

I believe that the original purpose of this radio was to fill the Family Radio System or the European 446MHz short range with limited power and a fixed antenna.

However Radioddity are targeting the hotspot roll where you are generally only a few meters away from the hotspot. So it has two power levels, 500mw (low) and 2w (high)

My first impression is that the radio is comfortable in the hand, but has a very light PTT button. So it's pretty easy to key the radio when you don't mean to! The battery life is approximately 2 days just receiving and around 8 hours on transmit on high power (2w)

The small form factor is a comfortable size, but that PTT needs to be fixed. The provided programing software is fairly typical for a Chinese built radio, it's not the best, but it does the job. It lacks any ability to import/export to CSV files like most other radio's support.

Anna Calvi – Odeon Theatre Hobart

I first discovered Anna on YouTube back in 2012 where she did a series of songs in the "attic sessions" What caught my attention was the way she was playing the guitar that was almost like it was a harp by using a circular motion when strumming the chords. The other thing was the sound produced just using a VOX AC30 and a USA 90's made Fender Telecaster. It is a clean tone with just a hint of breakup and lots of reverb. I figured that I'd most likely never get the chance to see her live, as living just out of Hobart Tasmania not many of the big names in the music industry actually include Tasmania in their touring schedule. But I was certainly surprised to hear a few months ago that she was to be playing as part of the Dark Mofo (organised by Mona) The evening was awesome! This is her second time in Australia, the first being in 2014.

Nextion 3.5 screen for Hotspots

I've used Pi-star now for around a year and a half. The first screen I used with the Zumspot was a 0.96" OLED screen (I thought it was awesome!) but after a while I started seeing other amateur radio guys were using the Nextion screen/s These are an amazing piece of equipment they run on 5v and have many uses, the main one I'll be using is the NX4832K035_011 this is the advance type. Basically the only difference between the two (normal & advanced) is the on board memory, RTC and GPIO available for use with external items (not used for MMDVM)

As you can see above there are six screens! I used a sheet of 400x400x8mm polycarbonate (plexiglass) and cut it down to make it match the border (25mm) There is still enough space to get access to the micro SD card for updating the screen code.

Here's the finished product in place, I'll need to do a bit of cable management as it's bit untidy but overall I'm happy with the end result.

Yaesu FTM-7250D

New radio day (well two days ago) I've been lucky enough to have been bought (birthday) the Yaesu FTM-7250D to replace the Yaesu FT-90R that has been in the car for almost as long as I've owned it! So far I'm impressed with the radio and its operation is almost identical to the Yaesu FT-70D hand-held.

Radio Features:

  • System Fusion-II Compatible
  • Operates Advanced C4FM Digital and Conventional FM modes
  • AMS (Automatic Mode Select) function automatically recognizes the signal as C4FM digital or conventional FM
  • Sophisticated Digital-Group-ID (DG-ID) Operation
  • Digital-Group-ID (DG-ID) Memory Feature : Up to 10 DG-ID pairs with alpha-numeric tags
  • True 50 Watts (VHF and UHF) Stable High-Power Transmitter with FACC
  • * FACC: Funnel Air-Convection Conductor (Wind Tunnel)
  • High Stability ±2.5 ppm TCXO Included
  • 3W Powerful & Clear Audio with Front Speaker
  • AMS with Multi-colored large LED Mode-Indicator Effortless FM and C4FM Operation – 225 Memory Channels with Alpha-numeric tags (maximum 8 characters)
  • Wideband Receive for 108MHz – 579.995MHz (108 – 137MHz: Airband)
  • Weather Broadcast Reception
  • Severe Weather Alert Feature
  • Easily connect with the WIRES-X linking system (Not support operation of WIRES-X Node Station)
  • Keyboard entry of operating frequencies from the microphone – CTCSS and DCS Encode/Decode, with split Tone – Versatile Scan features : VFO scan, Preferential Memory scan, Programmable memory scan and Dual watch

It's early days, but would I recommend this radio? Yes I would, because for the price ($399AUD) you're getting a dual band & dual mode (FM & C4FM) radio.
