BPQ32 up and running

I now have BPQ32 up and running. It was a very intersesting ordeal, but I am very pleased with the outcome. The site now has a node, BBS Mail and Chat, and Winlink RMS. I must thank Jeff WA4ZKO for his time and help in making this happen. This node is now connected to a node in Owensboro and Dry Ridge. Now it is time to build on this system and add users.

New Narrow band weak signal mode for LF/MF

There is a new narrow band weak signal mode for LF/MF by ZL2AFP. This mode is like PSK but not exactly like it. ZL2AFP CMSK  advances or retards the frequency to get a 180 degree phase shift in one bit period. The program window and waterfall remind me of The FLdigi program, only a little simpler.  I have not tried this mode yet but it looks interesting. For more information:

Some History of Digital Communications

Here is an example of how digital communications used to be. You can see how much technology has advanced.  Enjoy the video.

A Homebrew 2.4Ghz VSWR Meter

Here is a very good example of a Ham building a piece of test equipment. This would be very handy for testing HSMM radios. PE2ER did a great job showing the construction of this meter. Check it out.

BPQ32 for BBS and Winlink 2000

I have been looking into BPQ32 latley. I already have a Winlink RMS running and would like to have a BBS also runnig. BPQ32 looks like the right program for the job. This program is from John Wiseman G8BPQ/GM8BPQ. BPQ32 is an AX.25 NET/ROM compatible node software for Windows. This program will work with AGWPE software. This compatability is an asset for sound card based Winlink/BBS technology. This program does have a learning curve but there is plenty of documintation for it. I have been playing with it on my test computer and when I am comfortible with its operation I will start using it on the RMS gateway KC4BQK-10.

This proves the Internet is flat!

Optimized Link State Routing for HSMM

OLSR, Optimized Link State Routing protocol, allows mesh routing for any network equipment. This protocol uses multipoint relaying for optimized message flooding. OLSR is a good routing protocal for mobile ad-hoc networks. We an use this with our HSMM routers and build a permanent or a rapid deployable system. The system would be self configuring and self healing. These are some good points in using this protocol for emergencey traffic. The two biggest points are mobility and multihop. I am setting up some WRT54G routers with OLSR and DD-WRT and will start testing these units. In early testing it looks to be a good system.

60 Ghz and the Future

This is a good video about 60 Ghz and the future of LANs. Blogger Craig Mathias from the Fairpoint Group dose a good job explaining 60 Ghz and the difference between WiGig and WiMedia. This could be something in the future that could include Ham Radio.

January 2010 Haiti earthquake and HSMM

January 2010 Haiti had a devastating earthquake. One of the response groups, Inveneo, quickly set up an emergency communications system almost idetical to HSMM. HSMM is not experimental, it works and we need to embrace this technology. Here is a video from Inveneo:





We as Hams need to move forward and start building the HSMM systems.

HSMM-MESH

HSMM-MESH™ is a high speed, self discovering, self configuring, fault tolerant, wireless computer network. This is a HSMM project from Glenn KD5MFW, David AD5OO, Bob WB5AOH and Rick NG5V. I am looking into this software as a possible next step up from point to point, which is where we are now locally. With the help of some additional stations we could have a HSMM-MESH network for Henderson. This would be a great addition for Winlink and Weather spotting in the city/county. Check out the following links for more information.
