MythBuster presenter Grant Imahar passes away

sad to hear Electrical Engineer, Grant Imahar, one of the presenters on TV show MythBusters, has   passed away last week, aged only 49.     That was a  great TV show.   I loved it.  High technical content, great stuff.  The team on MythBusters made you think.   Up there with Carl Sagan's Cosmos TV series.

activity on TG4 P25 Network

 just to cover the TG4 P25 network, this appears to be pure gateway access with no RF repeaters connected.

users seen in the heard list today  VK2EVB, VK4APF, WB2PVY, VK5MDF,  VK3PR and VK6RO
Later on  VK4CUZ, VK3LTD  and VK4JAZ

more P25 activity for Sydney area 15th July 2020





that's P25 users today, KI6EBF, K5TRA, VK2PCH, VK2ERG, VK2FAEU & VK3FRJD that I could hear via VK2RCG 438.200MHz  and VK2RNS 439.975MHz. 

I believe that VK2RHP at  Horsley Park is also linked. It could be on 438.1375Mhz Output, 432.7375MHz Input. It is P25 only, with NAC, 0x293.

Hoping to see VK2RMB 438.175 added into the P25 network one day and along with all the other P25 repeaters in Sydney / Central Coast area.

TG10400 P25-NXDN Pacific Reflector

More stations appeared later in the afternoon, VK2FLAG, VK7BS, VE7IOX, VK3FKEN and VK3FPAR.


(click on the images to open and view in more detail.)


and even more people turned up at night VK3XEM, VK3JMA, VK2FJAY, VK2AJP and VK2DEK,
I think that adds up to 16 stations on P25 today.

new 2020 Honda Passport SUV

I just stumbled on this SUV from Honda in USA, its called Passport, it looks larger than CRV, but
has  3.5L V6 with 9-speed Automatic transmission and All-Terrain control,   wow,  not like the crap that that gets dumped in Australia that comes from Thailand with pissy little motors and CVT transmission. 

The Honda Passport SUV from USA

The Passport looks like a very nice SUV from Honda,  but a shame that we will probably never see it in Australia.

P25 activity in Sydney 9th July 2020

Out again walking my dogs at night, I often take my Uniden scanner to listen for P25 , well...  tonight yielded some good P25 activity on 70cm,  VK2ERG, VK2MPJ, VK3FJAW, VK4HG, VK7HSE ,
they were on the P25 Pacific Reflector TG10400, which includes  P25 repeaters 438.200 MHz VK2RCG  GPT Sydney and 439.975 MHz VK2RNS Hornsby, which I could hear both while walking, plus VK3FJAW was using VK3RMC 438.875 MHz P25 down Moorabbin area.   This is good, I starting to build up a picture of these P25 connections.

Zetland ARC - from Shetland Islands

I just stumbled onto a group of hams in the Shetland Islands and their Amateur Radio Club.
I found a ham several years ago, but he disappeared and so do his website, but glad to see more hams popped up in the Shetlands. 
I have interest in the Shetlands due to my ancestor originating from Toft, Delting & later at Haw, Gluss, Northmavine, arriving here in 1852 with his brother to work the goldfields of Ballarat.  They worked for P&O Steamship Co. (as did many Shetlanders) but bailed out when arriving in Australia to seek the riches from gold mining.

Anyway, here is the website
Zetland ARC from Shetland Islands

amazing, they have a list of hams, a lot larger than I ever found in the past.
I guess a few could be ex-pats from outside of Shetlands

DMR2P25 for Pi-Star MMDVM update

Looking very promising,   I just checked latest updates from the feature request discussion (as of 30th June 2020) for DMR2P25 ( that is DMR to P25 mode)  in the Pi-Star for MMDVM forum.
Thank you to Doug, AD8DP and Andy G4FDL for their development work in getting this new mode (hopefully) into Pi-Star.

DMR hotspots and 70cm band Satellite segment interference

I have mentioned in the past, about people operating their DMR hotspots on strange frequencies,  ie. some in the 70cm weak signal segments, some on the band edge where they are in breach of their license conditions, but I also seen in the social media circles of people running their hotspots right in the Satellite segments of 2metre and 70cm bands.

I mean, just because your low powered hotspots ( typically mW) cant be heard when you drive down the road a couple kilometres, doesn't mean it cant be heard from a overhead satellite. Yes, low terrain kills your hotspot's  weak signal pretty quickly, but to an overhead satellite, your little digital hotspot at home can be easily heard and therefore causes interference to other modes used via the satellites.

I can't comprehend it, are amateur radio operators showing arrogance, or ignorance, or just plain stupidity ?    Well, just look at the Brandmeister dashboard you will see lots of them,  operating their hotspots smack in the middle of the satellite segments.  It would make you laugh, if it wasn't so serious.  We (licensed amateur radio operators) are supposed to be technical minded, who sat for a technical exam, yet some of us,  have no idea where we are running out DMR/MM hotspots, with respect to the bandplans designated against our licenses.   To use a phrase that celebrity chef,  Gordon Ramsay would probably say is :  "This is F###ing Incredible !!"

So, here they are :
the 2metre and 70cm Amateur Radio satellite segments
145.800 to 146.000 MHz
435.000 to 438.000 MHz
that means you don't run digital hotspots or any other RF devices in these segments, unless you intentionally plan to operate via one of the Amateur Radio Satellites and the designated modes.




DMR to other digital cross modes and gateways for VK & ZL regions

here are some lists,  primarily created from Adrian VK4TUX's info page,
this is to help with those experimenting with cross mode digital modes.
This is focused on VK and ZL call  regions.
