If our modern civilisation ever were to collapse – taking with it global communication technologies like the internet, satellites, cell phones and undersea cables – with the right knowledge it wouldn’t be too hard to reconstruct from scratch the means for communicating around the world.

Test Run
Drove to Rochester last night with the new mag mount antenna hooked up to my TH-78A. It performed much better than anticipated.
While I didn't get any contacts on the way over, I did grab two on the way back on the 146.73 repeater. The first was with KD0DTU about 20 to 25 miles out of town. Came through quite well for the distance using a whip and 5 watts.
A little closer to town I picked up KB0ZBU. We chatted the rest of the way home.
I'd say that this bodes well for when I install the FT-7800R in the car. Imagine how 50 watts will perform.

Blog Check
Nothing to report on the radios. I just stopped by and noticed that the front page of my blog was not displaying any blog entries.
I'm posting this entry to see if it fixes the problem.

New Toys
Well, I'm back from Radio City with two new radios.
I picked up a Vertex (Yaesu) VX-150 2 meter handheld, and a Yaesu FT-7800R Dualband Mobile. I had planned on picking up the FT-2800M or FT-1802M 2 meter radio, but when I saw the 7800 on consignment for not much more than the 2 meter only radios, the choice was easy. Unfortunately, I think there is a loose wire in the 7800s mic which causes it to short out occasionally. I'll have to take it to work and see if Karl (WA0RLY) fan figure out what's wrong with it.
For power I picked up a SamlexAmerica SEC-1223 power supply for the TS-440S and the FT-7800R (if I don't put it in my car right away). Now I can return the power supply I borrowed from John (KB0SPM). This one should give my HT a bit more punch too.
Also among my purchases was an MFJ-1722 Ultralight 144/440 MHz dualband magmount antenna, SMA-to-BNC connector, DC cable for the 7800R, and a couple books.
Looks like I've got quite a bit of reading material to go through for the next few weeks.

Heading to Radio City
I'm planning on heading to Radio City tomorrow to buy a 2 Meter mobile rig, car mount antenna, power supply, books, and maybe a few other things.
Best part; tomorrow is their "Tax Free" sale. Not really tax free, but they give you store credit matching the tax on what you buy.
I'll post what I buy when I get back.
