or not? No test equipment or GP forum? Where would we slot discussion of an oscilloscope, power meter, SPA, real test equipment, or even s smoldering iron, ya no? Well, I've come across the Rigol series of Chinese equipment and it appears the DS1054Z is a really good entry level option, with...

Howdy All, I am considering selling off some test equipment since I have not been using it for years now. Wonder if there is any interest or what street value might be. The stuff is stacked out of the way so this is from memory: Tek 100 MHz oscilloscope (something like a 2232) Tek 494 spectrum...

I'm trying to verify empirical antenna gain figures and in the context of microwave frequencies, where I think ground effects are of less concern that typical at HF. I come across a HT "duck" antenna (5.4 GHz) that states it as a quarter wave with unity gain. How would this be expressed as dBi...

I built a fully integrated loop antenna crystal radio on a 23" diameter form (one slat of plastic/wood window blind). I like it because it is completely portable and does not require any additional antenna. 11 turns form the primary and 3 turns the secondary, small gauge phone line stranded...

Hi All, I have a Baofeng GT-3 and noticed that when in dual watch mode with the A frequencies set as the active channel, and with TDR-AB (transmit priority) set to A as well, if there is reception on the B frequency and you PTT, you will transmit on the B frequency anyway. Is there a way to...

Critical Thinking At Its Best! Woman: Do you drink beer? Man: Yes Woman: How many beers a day? Man: Usually about 3 Woman: How much do you pay per beer? Man: $5.00 which includes a tip (This is where it gets scary !) Woman: And how long have you been drinking? Man: About 20 years, I...

Just checking in on what's happening with DMR. Is it picking up on the worldwide? Is the CS700 the best bet right now, or are we shelling out for Moto? BTW, it would be nice if the search limit could be set to two characters instead of three.

I post this because it is timely, and it has bearing, plus, I cannot figure out how to actually find the guidelines. Is this the correct site??? http://www.health.gov/dietaryguidelines/ Where did they hide the link that reports the actual data, such as 400 mg of caffeine per day???

Ham radio. I want to tell folks about the merits. I understand them to an extent. What is the reliability of communication, say between the best mobile to mobile, mobile to base...at it's best configuration, and what would that be? Can it be a practical and reliable communication mobile to base?

No time to search if a dup, just found this:

Ok, what's the initiation?

I'm trying to make a T-shirt design and the creative designer has decided he wants a the image to appear from a vanishing point in the center. I set up a single point perspective grid in Illustrator and I can move my object to one of 4 planes. It looks like I need to split my image into 4...

the sites search results are omitting results with every subsequent search of the same term. The layout has changed slightly, and search seems to pick a category. anyone know how to fix it? I enter *fjr* and press enter. I saw many FJR motorcycles for sale from dealers and several PP. I later...

I've had this SS stinger for the broadcast band laying around with plans to cut it for 2m. My bike has a sissy bar, a passenger seat back, so picture an upside down U bolted just behind the seat. The top of that is where I bolted an angle bracket for the stinger. My first measurement is taken...

Is it possible to turn off the dual display/watch and make this radio use just one frequency? I'm fiddling with Menu 7 TDR and turning dual watch off, but I cannot see what it does since the display still shows both frequencies.

Just while setting up my APRS stations, I'd like to have a PC program that will decode the received audio from the mic (or line in) (and send data out the speakers). I recall there was a complicated configuration that required AGWipe and UI-View and something else I thought, all had to be...

Man, it took me a long time to find the Post New Thread* button! I'm sure that's me. I have the same problem with Yahoo! mail now that they moved the Send button to the bottom of your composed email, that's were I was looking for the reply once... OK, I searched for SDR, just those three...

I'm looking at antenna radiation plots and am seeing the octopus image for both E- and H-planes. I thought one plane was vertical, and that I would not understand the use for when discussing horizontally polarized Yagis, but if it were plotted I would expect more of an omni pattern. So what is...

Would you still have had it done?

I think 50% modulation depth is equal to 3 dB modulation depth. Does anyone know the equation for this? 90% is equal to 20 dB modulation depth?
