I'm just a city dweller without an arsenal because there's just no place around here to use it, but I've still got my Daisy BB gun, and I've managed to hoard 2400 Daisy BB's just in case!

eHam Forums / Satellites / RE: A question of trees

My QTH is on a small city lot in an old neighborhood, so we have lots of trees (old and new). A few years ago I tried working the FM birds with my mini dual HT when they were overhead. I could full quiet SO-50 and AO-27 with 140 milliwatts and the factory rubberduck antenna. My rig was the "Standard" model# C508A, and my secret to success was to stand on the round metal manhole cover (city sewerage) that's in the middle of the road in front of my house.

eHam Forums / Digital / RE: Too much info on PSK31??

I've been a casual PSK31 operator for exactly four years this month, and I don't like the canned "Brag" macro files. But, conversely, I'm appalled at some of the really personal info that folks type about freehand to complete strangers.

eHam Forums / Elmers / RE: FT-450/450AT 60 meter upgrade software
|

As the popular saying goes "I've been there and I've done that". I did a full reset (Home/RCL/Power) prior to upgrading from the old (0194) firmware to the new (0228) firmware. Then I did another full reset (Home/RCL/Power) after the new (0228) firmware was successfully installed. Then I manually reentered all of my CW mode customizations in VFO A and all of my Digital mode customizations in VFO B before I began my bench testing.

Bug Report# 1: I've given the new FT-450/FT-450AT (0228) firmware a fairly extensive workout into an MFJ# 260C dummy. The only obvious problem that I've encountered is that it always transmits 100 watts on 6 meters regardless of the power/mode that you've selected.

After fighting Murphy's Law for a couple of hours, I've successfully installed the latest (0228) firmware on my ancient Yaesu FT-450AT rig. I haven't as yet actually used the rig since the upgrade, but it did power up OK as 0228.
note: my ancient Yaesu FT-450AT was manufactured April of 2007 in Japan.
73 and good luck, Bob

I've had Verizon's Westell model# 7500 DSL wireless router installed for several years downstairs next to my desktop, and my laptop installed for several years upstairs on my radio desk. The physical location of the downstairs router is fixed and the upstairs laptop is fixed, and their 2.4 Ghz signal paths are approximately 12 feet line of sight point-to-point.
Questions: Why does the router signal strength change (good, very good, excellent)? Why does a good signal = 36.0 Mbps and an excellent signal = 54.0 Mbps?

eHam Forums / Mods And Repairs / Kenwood TH-215a won't power up
|
on: July 21, 2012, 06:04:58 PM
|

About 13 years ago, my Kenwood TH-215a decided that it won't power up from either a fully charged factory (PB-2) Battery or from the factory Cigarette lighter. Today, A Ham buddy of mine showed up at an Antenna raising party with his Kenwood TH-215a that still powers up, and now I've got the urge to repair mine.
note: I'm thinking that maybe it needs that little internal battery replaced, but any other repair suggestions would be greatly appreciated.

eHam Forums / Mods And Repairs / RE: Alinco DX-70T sticky transmit relay

OM's, thanks for the replies to my transmit relay problem, and maybe it fixed itself at least temporarily. How? I tried operating the rig in CW mode (straight key/semi-breakin), and that cleaned the relay. The relay doesn't stick anymore when I'm operating Phone with the factory (EMS-42) mike.

eHam Forums / Mods And Repairs / Alinco DX-70T sticky transmit relay
|

My 17 year old Alinco DX-70T rig just developed a sticky transmit relay problem when keying it with the factory (EMS-42) microphone. I took the microphone apart and spray cleaned that little PTT micro switch, but that didn't fix the problem. I can actually hear the transmit relay that is inside the radio sticking and then keying up.
Question:
If I take the covers off the radio, can I get access to that transmit relay to spray it?

I've been a MARS member since the first Gulf War, and all of the traditional MARS activities (i.e. Phone patches, MARSgrams, Guarding tactical freq's) came to a screeching halt during the Bosnian War. Why? Because that's when the US Military switched over the bulk of their comm's from HF radio links to Satellite radio links.

eHam Forums / Mobile Ham / RE: Mobile 2 Meter 1/4 Wave Whips Have High SWR but 5/8 Checks Fine?
|

I had a situation like this about 30 years ago with a 2 meter 1/4 wave magmount on roof of a '77 Honda Civic. Good SWR for months until the coax got damaged in the car door, so I cut off the 4 foot bad section of coax, then soldered new PL-259.
note: apparently the cut off coax was too short and had a weird harmonic length?

Wow! As a loyal Yaesu owner/customer since 1987, I'm definitely feeling like an orphan. Like alot of other Yaesu FT-450/FT-450AT owners, I've been waiting for new firmware!!! Maybe all of us loyal Yaesu customers should ban together and start an "Occupy Yaesu"?
