    LR44 battery question

    LR44 about 100 Ma. 357 about 155 mA. So the 357 will hold out a bit longer 50% more capacity. You decide if that is worth thee price difference.

    SWR Setting

    My Imax 2 K does 10 and 11 meter fine, even 15 meter where it is a half wave. 26,5 to 29.000 under 1:1.3 good enough for me 15 meter 1: 1.2. Horizontal OCF from Fritzel also works fine on 11 and 10 bit higher SWR but under 1:2.

    Build me a Ham Shack

    When i'm asked to build a station my simple answer is use 10% for a radio and 90% for the antenna farm. If you roll your own antenna's ( making them yourself) you can use the saved bucks for the radio set up. a mediocre radio on good antenna's = results. A 5 K radio on some mediocre antenna is...

    Solar Flux and Sunspot Numbers Finally Grow past 100

    We were above 100 a week ago, still no ironclad guarantee conditions will be good, with solar spots can come solar storms wasting conditions.

    Low pass filter use and linear amplifiers

    Your broadband ampwill amplify anything it gets in it's input including harmnics. Good tube amps like my Heathkit SB-1000 tou tune the PA and it will supresss harmonics and have a clean output if you don't overdrive it. Broadbanded amps don't have that tuning section and amplify anything that...

    Ameritron question on unit I purchased

    Digging deep in my old grey matter.. The al811 & 811h mod is SIMPLE. you cut 1 wire for the 10-12 meter mod, you will need to adjust input coil (inside amp)for lowest swr. if you do for 26.700 mhz, center of 24.900 & 28.500, you should be able to have acceptable swr on all 3 bands maybe just a...

    Do Tubes have a different sound than transistors?

    To put it a bit in perspective, most untrained ears won't hear 10% distortion, and very well trained ear can hear 2% distortion. As with audio a lot is personal, tube amps ( audio) produce soft distortion even harmonics which to our ears is soft distortion and we translate it in "warm" audio...

I'm running it from...

    Where do you get good jumpers?

    That is why as in my first post said i make them myself. Not skimping on good connectors and cable, taking the time to do it well, and measure twice and checking them for wear when in use.

    Where do you get good jumpers?

    Just remember what a set of new transistors in that shiny power amplifier or new tube will cost you if that jumper fails... i bet you then are sorry not to have spend some more on them for better quality ones...

    Where do you get good jumpers?

    I always make them myself not saving money on coax and connectors. Take the time to make them measure twice and test them out. Specially connectorss there is a lot of bad stuff out there chinese junk. Amphenol, silvered ones are the best i noticed after 45 years of making my own stuff, expensive...

    Not enough juice

    Alwways calculate with headroom. My ham station runs on a dedicated 230 volt 50 Hz line in the house with 16 amp breaker. That is 3680 watts raw power from the net available for the ham station alone. It runs a 30 amp supply for the Yaesu FT991A, again overcalculate amps for the radio (max the...
