Are Meteor Showers part of Space Weather?

We only have two observers in the southern hemisphere, Andrew K and Wayne VK2XN.

JT65-HF-HB9HQX-Edition
I've just downloaded the sourcecode and there's no way to compile on Linux.

So, there's absolutely no way to get it going on a Raspberry Pi.

Alan VK2ZIW

Standardize, it's the protocol we standardize on, not the software. Please correct me, if I'm wrong, but I didn't find anything for JT65 on Linux other than WSJT and WSJT-X, so I compiled up JT65-HF, results here: http://www.unixservice.com.au/hamradio/digital/jt65-hf/index.html I only use Linux mac...

Sourceforge has only the Windows EXE file:
But a little digging has Ver 1.0.9 DEBUG saucecode.
Had a little program execution problem, in "// Check dll version".
Running on Fedora 21 x86_64.
Cannot choose Audio Device, uses "Default" - this must be fixed.

So far, so good.

The Station Master has many dis-similar metal problems!!! The connector, brass, onto aluminium - disaster #1 The coil to baseplate screw, steel - disaster #2 The coil to radiater steel screw - disaster #3 The connector wire to coil, brass and steel - disaster #4 http://www.unixservice.com.au/hamradi...

There is no action on 52MHz, we SSBers are all on 50MHz
Beacons, FSK, WSPR, JT65 etc..

On 52MHz, we still have 52.525MHz simplex and 6m repeaters.
Put up a 5/8 vertical.

Our BMARC club has 4x 100W 28V Pager units, 148.025MHz
Easy to work with RF PA module, rest is junk.

Location Glenbrook clubhouse, in 19" racks 1m high.
Actual unit is 4RU.

Any interest?

Spent the $850, it will be worth it. http://www.vkclassifieds.net.au Do not limit yourself with a non-digital tuned radio such as the TS-120s from 1977. A digital display is no indication here (Many early Icoms do the display badly). Stability is needed for digital modes. The FT-840 in my collection...

The YU3UMV 23cm and 13cm transverters, a PDF of the VHF Communications article.

Sourced in South Australia in about 1988.

I have the VK5 23cm transverter 3/4 built, all RF working. 1W out, gave up and bought a s/h IC-910H with 23cm. (way to go with a spare $2000) Much more suitable for field day use. From Emu Plains here, can just make the Chatswood or Dural repeaters on 23cm, if I put my phased array vertical. This lo...

BMARC club has 4 x Pager transmitters with 100W 28V PAs. 148MHz.
A straight forward module with Motorola transistors in the output.
The p/s, signal generating and modulation section is junk.

At the clubhouse, they are clutter.

Anybody interested?

I have a 1m piece of 19mm x 6mm strip or bar, excellent, but HEAVY, HEAVY. 19mm x 3mm would be too bendy in lengths of 1.5m (6m 1/4 wave). The 20 x 10 angle 1.5mm thick for floor tile edging was very tempting for 6m use. Fly screen edging, a flat box section, is also tempting. If you have the 6mm, w...

Hi, You make it all way too hard. Just use small pieces of 6mm thick PVC sheet. Stainless (304) self tappers are, a dime a dozen. Nuts and Bolts supplier. Put one through your element, file the screw head and solder to the stainless. (Flux: CHEMTOOLS VIOFLUX ) Need a "U" bolt, 4mm x 0.6m t...

Can we have an idea what repeaters are using PCs or Raspberry Pi computers with
TCP/IP connectivity ?

Alan VK2ZIW planning to try a Banana Pi in a Tait 835/837 system.

Well, I built the adjustable loops as per http://www.cactus-intertie.org/LA/tec_not6.pdf (above) and they work, a treat. My loops are quite close, only 1mm apart. 5MHz pass-notch - yes. I made the capacitive wire probes pictured in tec_not6.pdf but could not get anything useful better than 20MHz pas...

Here is an antenna that can be both horizontal or vertical or with a hybrid, circular: See from page 128 and on: http://www.collectionscanada.gc.ca/obj/s4/f2/dsk3/ftp04/NQ56152.pdf Note these antenna can have aperture efficiency more than 100%. At 2.6 x 2.6 x 1/2 wavelengths in size, at 70cm and 23c...
