Dear Teropet, No, don’t worry. Be Happy! You can fiddle with the toroids and mess up a great radio or be satisfied with those power output readings…. Anything over 3 watts is excellent and the

??Dave, The best investment I ever made is the Donegan Optical Loupe. I had two from my medical practice. They are worth the money (the Donegan brand) but like everything else the Chinese

No because qrplabs reaches the specifications Hans writes. But I disagree that 2 db difference is not a lot. Just think about the efforts people do to have 2 db more gain with antennas... Merry xmas

Hi Aki and Evan, Thank you for your patience. Resistance between R2/3 and ground is 20.5 ohms. I checked the PCB for solder bridges with a sharp knife. I'm not sure if I made a mistake in former

I have bought a few months ago a JBC BT-2BQA soldering station with a few different tips. With this 140W soldering iron it was convenant to solder the QMX+. A simple and good tool for electronic

Oh boy do I have some opinions The Pinecil is the neatest thing I've ever seen and is top 3 best value items you can spend money on. $25 gets you an self-contained smart iron (with Bluetooth app)

I use fldigi on occasion - with flrig to control the QMX. In flrig, you set the config to talk to the QMX - there is even an entry for it in their 'rig' selection: Note that it is good to set the

No!? You should not be disappointed.? I get 2.8 watts on 20.? That was enough for 101 contacts in 41 countries at last month's CQ WW DX contest.? There's not that much difference between 5 watts

I would like to see salemans face when i ask him for 1 Mohm water.?
