How much time are you looking to hold the data?? Maybe they're better now but early ones had poor leakage current and would self-discharge in a week or less.? Also I don't know what's in the module

As the others have said, don’t cheap out on the solder, use a decent iron and don’t be afraid to use some additional flux. ?I typically use 0.5 - 0.7mm diameter as it’s a bit more controllable

I just ordered a midband QMX and I'm not disappointed because I will have the QMX unbuilt, I'm disapointed that I'll have to pay shipment a 2nd time. I will build both. I know that the QMX+ is

Like in the old days, soldering is all about the flux! Many inexpensive 60-40 solders and the newer (and not nearly as easy to use) lead free solders don’t have enough flux in them. This is why the

Hello, I did also sent a QMX for repair and alignment to Jeffrey. He did a wonderful job and the QMX is now up to specs. Bought the QMX used and was very unhappy with the performance. Now the QMX is a

For anyone wondering what the suggestion re revised bias was about, schematic given above. I? have used a known good schematic? and marked it up.? so there are no doubts it has been proven , at

I would suspect that there are quite a few people disappointed after just having bought a QMX. I wonder how many unbuilt QMX kits will appear on Ebay? -- Phill EA5JHA

At 106 x 55 x 146mm it is a fair bit smaller than a K2 and not that much larger than a KX3 so still eminently portable. In volume it is a good deal smaller than an Icom IC-705. Sure not the deck of

I find a really hot iron (3-400c) means you don't need to apply hest for long and the solder gets wicked through the layers nicely. So you need a decent iron that gets plenty hot. I use a fine chisel

Hello, while writing my reply in a conversation in Winfldigi forum, I realized there might probably be a bug in AGC implementation (not very sure, but see below). Maybe it is not exactly as what I

The developer blank slate leaves open many intriguing possibilities that were not possible on the QMX due to the tight confines of the case. Imagine putting something like a Pi-Zero in there! --

I just packed up two more of them and put the 6x9 envelope in the mail box for the morning pickup. -- Jim / K7TXA Eagle, ID SKCC 10447T BUG 301

Karl - are you telling me that it has not arrived????? Should been 2-3 days unless they’ve employed snails. Jim Bennett / K7TXA Eagle, ID SKCC #10447C B.U.G. #301

As soon as I saw the announcement, I jumped in and ordered one with all the trappings! I have build numerous QRP lab kits and every one has worked at first powerup. Hope they ship soon! 73 -Mike

Hi Foks, I've been soldering electronic kits together from as far back as the 60's with Heathkits. Started out as point-to-point connections, then circuit boards came along. Most of 'em were single

OK my friend - the new transformer has been wound (the old way) and will be soldered in on Friday. Wish me luck with power-up! :-) -- Jim / K7TXA Eagle, ID SKCC 10447T BUG 301

Possibly never. It is a goal that hopefully will be obtained but has never been promised.

Any reason not to replace the QLG1 battery with a supercap? -- Brent DeWitt, AB1LF Milford, MA

My rule of thumb is that 10dB power gain is the minimum amplifier gain worth bothering with. 73, Don N2VGU
