Has any one ever written programs for HP calcs that solve inductance, coil winding or any other topic related to amatuer Radio. My son and I have been building a tube radio and I was curious to see some of the interesting programs written for such items.
Thanks,Jeff

Hi Jeff, Great to see that you're doing a father/son project building a tube radio. Should be a fun project. You might want to try a search on the HPCALC.ORG site. I just did a search on "Inductor", "Capacitor", and "Resistor" and got several interesting hits. Not sure which calculators you're wanting to use. Found the following HP-33S guide to electrical engineering: http://www.hp.com/calculators/docs/guides/33sElectrical.pdf The HPmuseum site has following: http://www.hpmuseum.org/software/67resist.htm http://www.hpmuseum.org/software/33/33resist.htm http://www.hpmuseum.org/software/11serres.htm

> Has any one ever written programs for... Quite a bunch for the TI-59. That was before my HP days. Let me know if you're interested anyway. I've maintained my license, but have been inactive for 21 years. Garth

Hi Jeff, Once I wrote a simple program to do inductance based on a standard formula.
I would refer you to ARRL Handbook. Very practical "Bible" for
Once I had a HAM licence (as a young teenager), dropped my licence DW VK4Z.. ▼

I used to be GM4CFM but never bothered getting a licence once I moved to VK-land. Paradoxically, I got diverted into doing stuff with computers (partly due to the fun I was having with my -45 and -65) and ham radio fell by the wayside. I still have a 1978 ARRL Handbook on the bookshelf, though. Best,

From Les: "I still have a 1978 ARRL Handbook on the bookshelf, though." The first one I bought, which I still have, is from 1960, when I got my license, and I have one somewhere from 1946 that was originally my Dad's (and, I just realized, the same age as me). These are sort of like HP calculators - thay can be admired and used even after many years for their continuing utility (although finding some of the components might be a challenge! Do you still have any acorn tubes or selenium rectifiers?!). 73, Dave W8MIF/ZF2AZ (ex K3NXO)

"I still have a 1978 ARRL Handbook on the bookshelf, though." I also have the 1978 book, in fact! My father went out and bought it when I expressed interest back then. He had been active in MARS in the 50's as W3RTR, but let his license slide. We had both a National and a Hallicrafters full MF-HF reciever in the house when I was a kid. And a T-50 transmitter that we wanted to get going again.

Hi Jeff, There are a lot of hams on this frequency :-) Somewhere I scribbled down the ones I know of and there are at least a dozen regulars here who are hams. I suppose we really aught to set up a 20 meter sked one of these days--that would be fun, and a challenge (especially since I don't have a 20m rig!). About the only thing I ever programmed to do was antenna calculations. Nothing special--just keystroke saving routines. I loved building makeshift antennas with bicycle wheels and stuff. N3LPX

The HP65 EE PAC 1 has good coverage on inductor winding and other useful topics.
I can't find a copy online - anyone else got a URL ? ▼

Quote: I'm pretty sure it's on the Museum CD's/DVD; I have it here and if it wasn't, I would have volunteered to scan it earlier. (I could easily be wrong, though). Best,

Hi Les. Hey did you ever write for a '70's magazine called ETI? Just wondered if you are THAT Les Bell.. DW ▼

Hehe. Yes, I'm *that* Les Bell. Worked for ETI in London, then edited the mag in Canada and Australia. In fact, I got my job with the magazine on the strength of an article I wrote about the '45. Well, that and my ability to eat duck a l'orange. Long story. . . Best,

I just checked, and yes - the HP-65 EE Pac 1 is on the Museum DVD/CD's. What's more, the scanned version has my name written on the inside of the front cover, so I must have scanned it. That's the trouble with being an old codger . . . Best,
