Hi All, This is to the people that have streamed stuff like on U Stream using a laptop as the stream source. There is an obvious Mic gain slider for the sound...
The video properties are probably much more dependent on the camera hardware itself - if there's no sensitivity to low light, gain won't help as there will be...
Use a camera with good low-light level specs (<< 1 lux). Kicking up the video gain won't help a poor video SNR. And you'll have to provide some scene ...
How many of you have run into interface bugs with new laptops trying to interface with the RS-232 serial interfaces on TNCs and GPSs? I have, and I concur with...
Alternatively, source a True Day/Night CCTV camera with IR LED's. Most of the good quality ones will give around 10~15 of illumination in 0 Lux conditions. As...
I have a Kenwood TH-D7 radio I'm using with my RTrak-HAB. I'm using the radio to hear the beacon and make sure the HAB is working properly. I have the cord to...
... You could use a simple terminal emulator program such as Hyperterm or Teraterm to see the packets, and the data contained within. However since you are...
Iknow there is an formula somewhere but I can not find it. Like when making a open wire feed line the diameter of the conductors and spacing determines the...
Hi Joe, You've described a microstrip transmission line. A stripline is sandwiched between two parallel ground planes. There's probably something in the ARRL...
I have an OT+ SMT and I have the Speaker Mic Cable - Icom Type hooked up to my Realistic HTX-202. The cable is as follows: Red - Speaker White - Mic Blue -...
For those who sent a camera to the stratosphere. What setting did you find that worked best? I was thinging Tv Mode and setting the shutter speed to 1/750 with...
It looks as if you have it connected ok, but you need a PTT wire on pin #21 for it to key the radio. Try connecting the blue wire and possibly a resistor. Take...
Anyone got in the goodie boxes a DPDT relay they would be willing to part with? Preferably 9 vdc coil, but 12 vdc would also be ok. I have found several...
There is a very generic setting for taking photos in a bright daylight setting (no clouds, bright surroundings). You can view this simple method which used to...
Thanks for the diagram. I have tried with the PTT connected, but not with a resistor. I don't think my radio requires the PTT to hooked up though. I have been...
Yeah I have seen 9 volters in the past but not so much now. The reason for the 9 volt was a simple off the grid power activation capability. but on second...
Since it's a manual tuner, why not just use a dumb ol' DPDT switch? Or is the plan to drive the relay with the T/R signal? And it sounds as though you need to...
Not sure how you get it to work without the PTT. I have several OT1+’s and OT1+/SMT’s with HTX-202’s and Alincos and they are all wired using the PTT as...
Pretty good flight. What amazed me was after burst the PBC seemed to really tangle up badly. I thought this is a goner. But it cane down nicely. Joe WB9SBD ...
That is the way my OT+ has been wired for years.....no PTT. Have you tried it without? The OT+ has a jumper for HT, which I *think *enables the 2.2K resistor...

Aeronauts, The arhab.org website is going through a transition. The first step was to convert the membership list to a database instead of one really large...
While digging through some old near space videos, I came across one made by Lee Kelly of the amateur radio club in Twin Falls, Idaho. The balloon was tracked...
You'll notice that the parachute opens immediately and quickly drops out of the video (at the lower left) dragging a long fragment of latex. Paul ... -- ...
Thanks. I had forgotten all about the video. I was going through some of my old stuff to see what I could throw out. The credit really belongs to the...
