To be fair, the scope to which I think you are referring is geared for education, so the entry level student may well be seeing one...but yeah he does have a boat load of expensive equipment being tossed his way... Still a good resource. Soldering, I prefer Hakko, an FX-888 is a great one to...

could be or stuck relay

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...

I'm talking to a guy locally. I'm offering him a package for $500, but of course that is a convenience and broken down thusly ($50 scope, $150 SPA, $300 MA). The scope was booting fine this morning and would complete self test with 5000 WP failing. The SPA shows an intermittent PLL phase lock...

pics I'm kinda just wondering the interest and value. I think the 8901 is the gem in the pot. All this equipment is old and the scope issue is most disappointing... :(

HP8901B Option 002 is what I was thinking of, high stability reference. (and Option 004). I powered this unit up and all displays work. I connected a 100 MHz RF input and it measured to the last decimal. I do not have a modulation source to test right now. Tek 2430A scope has issues. First it...

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...

The FBI never needed apple to hack the phone. the phones have already been hacked, so what were they really after...? National Geographic Channel show Underworld Inc. — Season 2, Episode 7, titled ‘The Black Market' Another take on this though is, should there be warrentless spaces free from...

I found you a more gooder iron.

As I've always said, it's not important that you can hear me 40 channels away, but that you can understand me 40 channels away.

I wrapped all my spare ham and CB radio's in tin foil and buried them in the back yard just for such an event. And HAM most certainly is an acronym when used in proper context.

You can read the specifications on the Hakko site. The FX-888D uses a ceramic heating element, uses same tips as the FX-600, but I've not read much about the FX-600. I just prefer a station type iron for their superior performance, and the FX-888D offers a lot in a relatively inexpensive...

Hakko makes a great product, well respected and I'd say best in class. I prefer the station type irons and went with a 951. The 888 is very common in the electronics hobbyist arena.

So far I've been OK with the R820T + RTL2832U Interesting comments here: http://swling.com/blog/2015/03/wyn-compares-the-sdrplay-rsp-and-airspy/ Particularly, "You can Google for several video’s made by Leif Asbrink on Youtube who has made a series of benchmarks wich points out the not so...

I was thinking of vertical dipole: | vs L but also extending the idea of the L to a ┴ and then further to 4 radials, to infinite radials.

I knew this was going to happen. I have wiki, WWRF, and two real RF engineers supplying info, and I have four different answers. I was thinking a 1/4 wave has equivalent gain to a dipole since you can bend a dipole 90* to make a 1/4 wave vertical.

Thanks for chiming in. The DB, do you mean to state the dBd and dBq are respectively 2.15 and 0.15 dBi? Since I am just presenting empirical data, I would take these in reference to free space.

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 think the competition x-tal DX-ers don't even like to use cardboard formers because they can absorb moisture. "A PVC form can be used, but its dielectric has about 4-5 times the loss of the styrene form and will reduce Q, especially at the high end of the BC band."...
