Just a general tip that has helped me, I bought a flux pen, its a felt tip marker with flux. For soldering SMT components Just apply it to the spot & pads, the flux helps hold the part to the board

I thought I'd also mention picking up one of these some time back when I was in a bind, did not have a lot of extra funds, and needed something besides solder wicking and/or solder plungers, neither

Tony,? I have used this soldering station for years without a problem? about30-35 dollars on ebay. 937D+ Electric Iron Soldering Station Paul Hello Tony, I wonder if you have changed the type

I have an old Weller 25 watt soldering iron that has been hanging in there forever. I've probably had it for 30 years. It does fine. I have found that it helps when soldering surface-mount devices to

Hi Tony, I ran into the same issue last year when trying to solder some thick gauge wire to XT60 connectors.? My solution was this: tinyurl.com/4b7anbhj To my surprise, it's lasted nearly a year

Hi, I have found from time to time I need to remove the tip and use a brass wire brush on the tip AND the part of the soldering tool that mates with it. The oxidation (may look like 'mere'

I have had the same experience with three Weller soldering units. Sometimes one gets hot enough then not so much. It could be the tip which can be changed although I haven’t tried that since

Hi Tony, is the iron thermostatically controlled? If so, increasing the voltage may make it heat up quicker, but not make it hotter. 73 Nick

Hello Tony, I wonder if you have changed the type of solder? I still use the "hazardous" lead/tin, the later lead-free is not nice to use. Otherwise maybe someone could recommend a

Tony,? I have to ask where you are getting/got these cheap soldering irons.? I bought one from an ebay seller (Chinese) and one from a supplier here in the USA that said it had a USA power plug on

Good Morning Group, Here is a related question concerning building Softrock circuit boards using inexpensive soldering irons. I have been doing such building for lots of years, with hundreds of the

Sort of related - I need to make an attenuator for my FT817 on transmit as a 432 MHz microwave IF radio. I have the appropriate carbon-film resistors. I measured them on my NanoVNA to see what they

Roland, Thanks for looking. It seems whenever meters like the LC-100 are mentioned for use with HF Ls and Cs someone pops up inferring that the few 100s of KHz they use will give wrong readings. I

Your question prompted me to actually look this up. I own a GW Instek LCR-916 which operates between 100Hz and 100KHz. The manual contains a page-long list of accuracies for different L and C values

Ok,looks like it made it.? Not sure what's up.? I had to change stmp from verizon to aol and, so far, the only way I can get the accounts working again is to go into AOL and use them to generate an

Sorry guys, just a quick test to see if my email makes it to the group.? I don't know what's happening with the Verizon-AOL relationship lately, but about 2/3 of my accounts stopped responding.? Not

That is therefore 50dB below peak which is not an excessive figure. It is a long time since I tested mine so do not remember my estimate. My theory was imbalance in internal capacitances. I seem to

At 1W PEP... 20*log(0.06/20) = -50dBc

Alan, tnx for the fast reply. The -20 dBm is measured with a 200 MHz scope: 60 mVpp sine at ANT -> "true" power and is verified with an R&S FPC1000 Spectrum analyzer. Mixer works fine, and TX IRR is

Felix, It is normal for the LO to be present at the antenna. On a RX close by it will seem loud. It will be present at a low level on TX. How do you measure -20dBm? Below full carrier? I have never
