I have a Pixel 9a, my wife needs a new phone, so I thought I'd get her a Pixel 9a also. I bought mine 1 yr ago, it seems they are now $100 to $125 more. Anyone know of a sale or a discount coupon.
Brother in law has been doing HVAC for years on his own. He is now 82 and still does a little here and a little there, This morning he pumped down a a line after my son and I installed a mini split in his home. Everything went well. I knew he would not expect to be paid, so I slipped and envelope with $80 in his van. I watched him so he wouldn't return it, but some he drove off and the envelop was still with us. So, he was complaining about his gauge's, not being good. I want to buy him a new set off gauges. Is there any particular brand I should get. I don't want to go cheap, just and industry standard gauge would be great. Maybe even have Amazon deliver to his house, so he can't return it locally. Thanks
In my quest to measure 75Ω TV equipment with a 50Ω NanoVNA. I want to build a two twelthwave transformer centered on 539MHz, Here is my first attempt. Rather than the expected 50Ω, I got 25Ω. I removed the F connector and solder a surface mount 75Ω resistor, the Resistance at 539MHz increased to 38Ω. It leads me to think I need to include the connector in my length. This very dependent on cutting the cables to the correct length accurately, because the are short. 1.176 In and 1.517 in. The only other build direction I can find about the connection between the two coax pieces is, leave 1/4 inch and solder together. That may have no effect at 28MHz but at 539MHz , I think it has to be accounted for, but I don't know how. Anyone have input on building this with connectors installed and how to account for the length with connectors?
Trivia, The other problem I'm having, I have tried several RG6 or RG59 and haven't found one with a copper shield, I can't solder to the aluminum. So at this point all aluminum connections are just compression. I'm still looking.
