It's amazing what smartphone tech is capable off. I'd be keen to check it out. Building a short wave supereganerative (rx only) circuit, a SDR, a pair of amps, pre-amp, the parts to finish the parabolic antenna have arrived so that will be completed soon ( need f uhf to f uhf Conn's to finish, jaycar tomorrow) plus other stuff as always. Studying is going well, so hopefully soon I'll be licensed and on air soon, plus able to build tx/RX circuits too. Car has a new battery so I'm mobile again. So I'll see you at the club and on rides if you're there. Keep up the good work and research, I appreciate hearing about achievements and advancements not only the broader smet community has to offer but more pertinently what members of our club have acheived and tried. Cheers Kevin ta

I downloaded a heap of YouTube remoting videos, viewed them, and decided to install PocketRxTx on my phone. It and the videos looked impressing so, after downloading the User Manual, I then decided to upgrade to the Pro version for $5.00 odd. This allowed me to control a couple of Web SDRs without doing much more than opening the app and setting a couple of things. I tried a couple in Canada and the app creator's SDR in Hungary(?). Worked a treat. The manual says that there is nothing really different with controlling your own transceiver and this is next on the list when I get some time.

It seems like an easy, painless, and cheap way to go.

Remote Control #remote

Another spin-off project suggested itself to me after rain put paid to my trike building endeavours for the day.

Why not remote control a home multi-band radio from your ride? The benefits are less stuff to cart around and the more efficient, higher gain, antennas that exist at home. A Raspberry Pi based computer might be the best to use at homer as it would only require starting up. There a many Youtube tutorials on the Internet. Only require choice of which one to use.

You can use your phone to control it. I have a dongle that I use for DMR so an old tablet, when I get around to resoldering the micro-USB socket, should do for the ride end.

How about it? Let me know how you go and I will copy it.

The first rider in the Lyon-Canton solar bike rided has arrived in Guangzhou (Canton). 12,000km in 45 days = 270km per day. Think of that next time you are too tired to ride around the block.

Mudguards - Plans or designs for recumbents

Bog, from my experience requires a rough surface (80-120 grit) foothold and a chemically sterile (i.e No wax, grease etc) surface to perform a good bond, but even then you have to consider your hardener ratios, humidity, temp, and material permeability, flexibility to gain better performance. even then bog under ideal conditions does not like temp variations, heat, dissimilar materials (i.e metal and plastic in the same area to be bogged), substrate surface expansion (ie. sheet metal on a hot day) and especially, shock and vibration. An alternative maybe fiberglass, resin, carbon fibre or 2pack polyurethane resins from easy cast which is like castable pvc in a way. it files, joins, flexes, and stands up to more abuse than bog. But with steel, Alu etc weld smoothing bog is still king due to these parts made by common ferrous and non ferrous materials usually are rigid non flex stable components i.e vehicle non structural sheet metal if the prep is done right that is. I've used "easy cast" (2pack polyurethane resins) before on similar pvc projects and found it vastly outperforms, compared to bog. You can by these easy cast kits from Riot art supply for approx $45 Aud or online i guess for less, these kits come in various sizes from 250mL to 1L and comprise of instructions of use and part A bottle (resin) and Part B bottle (hardener/catalyst/ accelerator). You could even buy silicone mold kits and "pour" one piece parts from scratch using easy cast a silicone mold and a clay die (original relief cast for the silicone mold). Hope this helps.

Before anyone gets too carried away with making mudguards, it may pay to consider the bogging process.

My single mudguard was left sitting on a bench awaiting time to progress it further. Unfortunately, I knocked it off and it fell on the ground. Many of the bogged kerfs cracked with the bog and the PVC separating. Maybe PVC is something that PlastiBond doesn't like? I have used it for filling welded steel to make it look better where the angle grinder wouldn't fit and it is OK.

Internet radio receiver netcasting websites

G'day fellow radio, electronic and cycling enthusiasts, firstly i'd like to extend my gratitude of welcoming me to the club and also making me feel accepted and additionally providing me with valuable advice and resource materials. Secondly I'd like to say and thank everyone involved with today's bike ride, although short and the weather was not ideal, i still had fun. Now to my point, recently i have been introduced to internet amature radio "net casts". I was searching for the 'KIWI' site (unknown actual name), if anyone can refer me to this site, it would be much appreciated. By chance I did stumble across a net casting of The Irving Amature Radio Club WA5CKF located in Dallas, TX, USA. At the moment a weak signal is broadcasting a sci-fi movie, mainly soldier, bladerunner, terminator etc forum chat, interrupted occasionally by a clearer broadcast between two gents with thick Texan accents discussing amature radio setup, disign, and troubleshooting, with very very occasional morse transmissions. Just thought i'd let you know whats out there that i've found. link as follows http://streema.com/radios/play/49163 additionally STREEMA has other amature radio net casts see link for more https://streema.com/radios/search/?q=amature+radio . I hope this is useful, if not it's at least something to keep in mind for later, if needed  i guess. Any way I hope your day is going well and again thanks for the welcome to the club and advice in my new found love of ammature radio. cheers Andrew.

Two photos of my attempt to make mudguards have been uploaded to the Tricks and Hints Photo Album. The rest should be relatively easy, although nothing was hard or difficult with what I did.

I suddenly remembered that I had planned to make PVC mudguards. Similar to defective windscreen wipers, they only show as a problem when it rains.

My plan was to slice a PVC tube lengthwise, kerf one half, bend it around the wheel using a hot air gun, let it set, fill in the kerf slots with "bog" or similar, sand, paint, and attach over the wheels to suit. I still have to do it and should do it sooner rather than later. Watch this space. Might get started this afternoon.

Thursday ride. Might be a bit wet for it but a possibility of a ride on the O'Keefe Rail Trail towards Axedale to meet another ride from Axedale towards Bendigo in the afternoon.

I'm sure he will finish it during the 'afternoon' shift ;-)

Good to see some activity. Congrats to Sean on his maiden voyage with hopes that it is the start of many? What about it Sean?

I wish we could have. Still waiting on someone to finish electrifying his trike.

See the attached image of Thursday's ride with Graeme and Sean.
Sean rode from White Hills to Spring Gully and return.
Unfortunately the coffee van had left Lake Weeroona on our return journey!
