In the future, you might want to consider adding a $.99 audio output transformer from Radio Shack.  This will better match the low impedanc eoutput from the rig to the high impedance imput of the PC's soundcard.  It will also isolate any stray RF from the PC.

Yes, the will work, after a fashion.

I have the new AT&T Tilt (HTC TyTN II - Kaiser).  I run PocketDigig on it with success.  Like a fomrer responded siad, you just need to get it in the proximty of your rigs speaker and it can pick up the QSOs.  The mic is extremely sensitive and the software filtering allows it to operate in even somewhat noisey environments witht eh rigs volume set at only 15-20%.  To transmit, I just key the rig's mic next to the Tilt's speaker.  Very cool.  In alot of situations, I not going to bring a laptop. This will work.  Folks in South America are already using this software and smartphones with their 5W QRP rigs.  All folds into a small corner of a briefcase.

The old APRS/CE program will work, but does not seems to comprehend my Kenwood TH-D7(G)'s TNC, even though it has an .ini file for it.  In the event, the map supply for the old program is limited and "sketchy" by our 21st Century standards.

Right now, I'm working on a BT connection to the Kenwood through th Gamrin Mobile XT running on the Tilt.

In general, if you have not changed the color settings, the change in color is a reflection of singal strength that Digipan receives.

Have you adjusted you line-in signal levels? Your antenna, or the rig's audio output levels?

When I had a 900 MHz SSTV beacon up and running last year, I used my webcam/weathercam as the video feed.  It was just pointed up as the northern sky at 1 frame/minute.  For that I used ColorPix software.

I used the same camera simultaneously on a website created with Active WebCam software...

They also offer a free dynamic IP forwarding service when creating a website with their software.

I have a different take on this same symptom you describe.

My AL-811 followed the same pattern asyours.  It blew one, then both fuses.  The lights would flicker and the relays would chatter.

I replaced the fuses and did a thorough dusting of the insides, and cleaning and re-seating the tubes  (as they cycle through warming and cooling they can become loose in their sockets).  After this dust-off, I have had few problesm.  

Ameritron replaced all three 811As?  I haven't replace one in over three years of owning the amp, although I have replaced 4-5 fuses because of dirt.

This is an interesting thread.  When I was a Novice in the late 1970's, I learned the 100W light bulb dummy load concept from fellow hams.  It worked great for roughly tuning the finals in my Heathkit Novice xtal transceiver onto 40m.  

I remember I could us it for code practice at a certain power.  Not only would the light flicker to the rhythm of code, I could use a cheap SWL receiver to pickup the weak radiated signal like a buzzer.

Increasing resistance is one way to describe the change of an RF-excited light bulb.  Another way is as a current-loss device.  As the the light bulb is excited, it begins to radiate across the EM spectrum.  Infrared generates heat. RF generates my little code-practice device. And of course, its main purpose, generating visible light.  All these radiative relaxation processes dissipate the energy of free carriers (current). The lost energy and current can then be thought of as increased resistance.

There are cheaper eTrex models that ARE serial (~USD130.00).  I have one and use my TH-D7(G) wiht it.

KB3MTV,

All post-1995 cars have a number of on-board computer modules, more or less susceptible to high power RF energy.  Ususally the figure given by US manufacturer is anything >100W HF.

The ARRL website's quote from SAAB is unhelpful...

"All Saab vehicle designs have been EMC tested. Individual questions about frequency and power can be answered by their Customer Assistance Center. All inquiries and problems are handled on an individual basis. They have no record of any EMC problems with Saab cars. The installation of after market accessories will not void the vehicle warranty, but if the installed equipment causes any damage, that damage will not be covered under warranty."

Guess you better contact Saab.  But until then, don't run mobile.

VA7CPC,

HWat's your address again and when do operate?  I can solve her...er...your problem, OM. Hi Hi!

Ed,

You've probabaly already tried something (two weekends have passed).  I would suggest you shunt-feed the copper downspout.  Its all proabbaly grounded, so a nice capacitive shunt-fed tuner would do the job.

Now, get to work!  Hi, hi!

OMs,

I have learned something more about the capacitive reactance in coax and HF mobile whip antennae in reading this forum topic.  I'd just like to respond to the original question back a page or two.

I was fortunate enough to purchase the entire Iron Horse series of mini-HF (spirally-wound) antennae before they ended production.  These are the equalivalent of, not a "wet noodle", but a "half wet noodle" radiator.  Despite their poor efficiencies, I easily enjoy world-wide QSOs with the 20m mini-HF (about 25" tall) mag-mounted to the roof of the SUV with 100W input.  I have tuned the stinger to match the middle of the 20m band to my TS-480SAT w/o auto-tuning.  I then insert a small Versa tuner and tune it until low SWR is achieved, again.  In this fashion, I am able to then use the TS-480SAT auto-tuner to tune the entire 20m band while mobile w/o further manual adjustment to the Versa tuner or stinger.  Of course, all this is at resonance.

I also work 60m.  I did this by replacing the stinger in the 75m mini-HF if a "cut-down" version. Inserting into the coil, I folow a similar procedure in tuning up the rig. It all works fine throughout the five channels on 60m we are allocated.  The efficiency is horrid, but the antenna appears resonant, and radiates.

When mobile I have my FT-8800 scanning local repeater channels.  It also scans past the "Home" frequency of 144 MHz pre-programmed into the unit.

Whenever I pass a fast-food restaurant, some grocery stores, city hall, etc., the scan stops on 144 MHz and what sounds like a huge noise level breaks the full-on squelch.

What is overloading the receiver?  Is it MURS frequencies, or what?  And why stop on 144 MHZ and not another 2m frequency?

ThanX!

The direct, bottom line reason is the sinking value of the US dollar.  As of today,

1 Euro = $1.28
1 UK pound = $1.88
110.5 Yen = $1.00

These represent the worse rates against the Euro and the GBP in years.

Despite Ameritron being an American manufacturing company (as it name implies), it imports both parts and materials.

The devalued dollar has also increased the market value of Japanese and European gear.  Since it's a market-based economy, the market value of the AL-811 is also increased.

It's not greed.  It's just the working of the free enterprise system.

Stick to the simple.  A solid-colored polo shirt with ARES/RACES logo on left or right breast pocket.  All other clothing should be fit for the assignment, or potential assignment, and persona.

This has worked many years for us in the Emergency Services Department (ESD) of Burning Man. Dispatchers, Fire Crews, and EMT/Nurses/MDs all wear the same "uniform" polo w/ ESD logo.  All are easily ID'd by participants, other volunteers, and LEs.
