Here is a copy of the original NC40a manual. Hope this is of some help

Please be careful using higher wattage bulbs for dummy loads. I fear someone’s hearing may be damaged if you were to use a 1KW projection lamp with a 1 watt transmitter, not to mention the possible da

Happy belated 77th Birthday Jim and I hope many more. I think it’s great that at 77 your still on the forefront of technology. I hope I can do the same when / if I get to 77. 72s 73s and of course the

Good afternoon all I have a question and hope someone in the club can help. I was watching Ham Nation last night and in Bob Heils segment he was demonstrating his new Ameco AC1 transmitter kit. As par

WOW that’s impressive. I love really small radios so much that I have two ATS 3 rigs in altoids tins. In fact I have a lot of gear built in those tins. Ok ok it's a bad habit I know, but it's better t

Paul K3WWP operates exclusively QRP at 5 watts as does the people he operates with. I am unsure if filters would be required with QRP rigs operating on different bands using separate antennas. I did s

I went to the web site to get some info on the 2019 Ozarkcon and find the registration for 2018 is up but not the registration for 2019. I am planning on attending in 2019 and am wondering when regist

I’m glad I don’t own a Dollar Tree franchise.

I just looked at the 270 items, It looks like most if not all electronics products are included. Items include I.C.’s resistors diodes multi meters. Ect.

Bob I hope what I said helped. Please let me know if there's anything I can do to be of more help. Best of luck with the General exam, and I look forward to rag chewing on CW with you.

Well the answer to your question depends, 1. What type of antenna are you making? 2. What is the intended frequency of operation? 3. Is it to be fed with 50 ohm coax? 4. Is it a full size radiator or

Jim I just bought a model BM4070 off ebay (NEW) for $26.95 which includes free shipping. It arrived in about 5 business days. I checked it out and it seems to be reasonably accurate on low value (pf)

No worries Dave, I found the 328P’s on ebay from an American seller with the Arduino R3 boot loader installed. I ordered 3, I think they were around $5.00 each + a few bucks shipping. I really don’t c

Good afternoon Dave, I have a question about the ATmega328P-PU micro available from Mouser. I would like to purchase another micro chip and load the latest version of the firmware using an Arduino uno

OMG there is an epidemic of that also. W3BNO

GM Dave and all in the group. I took a couple days off to extend the 4th holiday and used some of the time to build the Hilltopper kit. I followed the manual verbatim, doing each section in sequence.

Regarding the dummy load idea, Back in the days when I was running QRO (100) watts, I made a dummy load by immersing 20 1Kohm 2 watt carbon resistors in a quart of mineral oil with a SO239 mounted to

You don’t need a specific calculator, Just keep in mind that for parallel values of resistors the equivalent resistance will always be lower than the lowest value of any one resistor in the parallel c
