Hey Gil,

I have the MR100 also and have had good success with mine. In your video review you said you would post the graphing software somewhere? In any case I cant seem to find it. Also, my power switch is down in the right bottom side of the tester, where yours is on top I noticed, otherwise everything seems to be the same.

Batteries & Solar / Re: Best portable battey pack for QRP HF/CW
« on: May 12, 2017, 11:05:00 AM »
Gil,

I took my first Gateway Laptop battery pack apart and found 2 bad cells out of 6. The other 4 have 3.7 to 3.8 volts on them. I'm charging them one at a time in a cheapo Chinese 16850 charger for my LED torch. I will look at the charger you suggested and read up on the 16850 chemistry to see how to properly charge them. I know multiple battery packs need to use some kind of load leveling circuit, so I will investigate that as well. Thanks a lot for the tip.

I grew up in Chico, 18 miles north of the Oroville Dam, so upstream😀. We used to take field trips in school to the dam when it was being built in the early 60s. Since then I have run Telecom cables inside of the dam itself. If it ever breaks is going to be a big deal with a lot of life/property loss. I never understood why the emergency spillway was made out of dirt. It just stands to reason that if water went over it it would wash the earthen made dam away and breach the dam, and I dont have a engeneering degree:-) I guess they never though they would have to use it.

Hi Gil,

That is a good idea as im a computer tech and have a whole pile of bad laptop batteries that I could slavage them from. Now to build or buy a sutible charger for them. Thanks for the tip.

Batteries & Solar / Best portable battey pack for QRP HF/CW
« on: May 11, 2017, 06:46:24 PM »
I'm sorry for asking this again, but is there any new technology in the way of portable battery packs? what do you all recommend? I'm tired of getting burned, (literally), from EBay LiPo packs, it seems they are all garbage. I have been looking at LifePO4 packs but they are so expensive. Any recommendations? I only want to run a 8 to 10 watt LNR Precision FX-4A for as long as possible at 11-12 volts with as little weight as possible, (I know the same thing everybody wants).

I see the Chinese have copied Chris's mcHF transceiver. http://www.ebay.com/itm/2-8-Color-LCD-QRP-HF-DIY-Kits-for-mcHF-SDR-Radio-UI-0-4-Manual-/141874369625?hash=item21085f1459:g:TrwAAOSwZG9WkyaV
I don't think I would touch this with a ten foot pole. I read that this was done without his approval and violated the Open Source rules.

Classifieds / SOLD!// Hendricks Kits BitX17A 17 meter QRP rig
« on: November 21, 2015, 06:06:32 PM »
Hi all,

I'm selling my Hendricks BitX17A QRP transceiver professionally built by me. I have mounted it in a nice compact slim blue case with a N3ZI digital small blue display for frequency readout. Email me directly for more info and pictures at caulktel@gmail.com I just recently made a contact with a Russian Ham at Mirny station in Antarctica with it, running only 8 watts. It works great! Asking $100 PayPal, buyer pays shipping.

I want to build one also, but I wish Chris would sell it as a complete kit without having to source the finals and the case. I know it seems trivial, but I don't want to spend $400 only to find out I still need to find more parts. I only want the the metal case. I think the printed ones are ugly. My .02 worth.
