Greetings, all... I have a family emergency and have been regretfully forced to sell my RX-340. I am wondering what a reasonable price is for it. I need to sell it in a big hurry but selling it for t

2. [TenTec] Orion II ad in QST (score: 1)

I'm risking my butt by stepping into this one, but, what the hey... Am I understanding this right? People are getting upset because the ad is showing something that isn't an Orion II? Take another lo

It's all about accuracy and precision -- both at the same time. Now, if you *really* care, you'll calibrate your system to read in Janskys. *Then* you can compare results to each other. (1 Jy= 1E-26

I think that's the same thing as I said but with different notation. per = /, 1x10 -26 = 1E-26 Text is inconvenient when doing math formulae. :-) Eric -- Eric F. Richards efricha@dim.com "The weird p

I can't speak to the SDR 1K because I don't have one. However, I was an early adopter of a much less capable radio, the WinRadio G303i. It's an SDR that brings an 11kHz IF into your sound card and do

May I throw in a contrary opinion? I'm running on 800 AH (24 VDC) of hospital pulls. They saw one year of service and were yanked. 80 AH gel-cells. The inverter is an Exeltech XP-1100 (1.1 kVA) -- to

Most inverters today -- including a properly designed sine-wave inverter -- are 85% efficient and up. The power supply is a different matter. This is based on running a 500 W space heater and measuri

Well, what can I say? So far my milage has been pretty good. :-) I sank the most money into the PV panels and inverter. There are so-called "sine wave" inverters that put out a nasty stepped waveform

Measuring an old Exel. SI-500 (12 V input), we ran the input from 10 to 17 VDC and got 117 to 118 vac in a nice clean sine wave. I don't know if you can do better than that... Lest I be called a shil
