Hi Don, Well I can't see spending $150 for an LC meter although it would be nice to have one. I'm not really a electronic tech by any means so it's really hard to justify the expense. And from a

I did some searching and as you said the short answer is yes, but some of the discussion I saw indicated that for each change in feedback voltage, the program would have to be

I haven't done that, but once I was talking to NU0Z on 2 meters while being parked next to him in a parking lot. The sad thing was that we were using a repeater about 20 miles away. -- Tom Sevart

Really, you find the EZNEC manual poorly written? I actually think Roy did an outstanding job with it (I have no financial interest in EZNEC). Of course, I will point out that antenna modeling is a

Hi Steve, I assume you know the ultimate inductance of the coil you are winding. A handy tool to have is a L/C meter. Not all toroids are alike and it is always a good idea to measure. My guess

Has anybody measured the impedance of the toroids used in the PigRig? The binocular toroid is driving me crazy. I think I have it correct now, but I would sure like to verify it with an impedance

Short answer is 'yes' long answer is a bit more complicated. As an example, you can model a crystal oscillator, but as all the components are "perfect" there is no noise in the resistors and

 Very little to it and very easy to do as long as you goslowly and follow each instruction and looking at each picture . My main problem was I was trying to look and think ahead .Went back to

I have wound the small roid twice. The wires are like they are supposed to be but I am still not sure if I have "6 full turns on" Paul N0NBD Sent from my iPad

 Hi Barney..............spice is a software programfor simulating circuits. Yes, you can use it to simulate a regen ar audio or RF.If you wish I can send you a short article about that that I did

Pins are only for the crystals..not the toroids. 73 de K0NEB Sent from Yahoo! Mail on Android

Would this work for a regenerative radio? Barney

Interesting. I have Sip pins in for the crystals, but hadn't though about doing it for the toroids. 73 de Lee KM4YY

Thanks for the info Tom. I will go to the website and print them out! Bobby Kb4qnr Sent from my iPad

I got my start in LT Spice with the QST Column Hands-On-Radio. There were at least three articles (somehow I thought there may have been a fourth one) and all are available for members in the in-line

It took me two tries to get the small binocular toroid right too. It is a bit confusing at first but isn't too bad once you figure it out. I just have resistors in and sip pins besides the toroids.
