Steve - using the Bird 43 originally with 2-30MHz 1Kw 1000H insert on 475kHz, and then compared it with a 1Kw 1000P 450kHz-2.5MHz insert and maybe (maybe) the 2-30MHz insert was showing low about 10%
Hi Laurence, I have tested a 2-30 MHz 1000H slug on my Bird 43 on 475 KHz and he need about 2.2 KW to read full scale on the meter with clean sine wave signal on 50 ohm dummy load. I think that not a
Hi Steve, I found a lack of sensitivity with my 1.8 - 160MHz Welz SWR/PWR meter on 630m, so not much good for a few watts, probably OK with high power. I found the best solution was to build one. Chr
Many thanks to all of those taking the time to reply to my inquiry. It seems that results vary depending upon what meter is being used but it sounds as though only a few are having reliable / accurat
Hi all Adjust your tuned antenna matching transformer to give maximum current in your " L" or "T" antenna up lead. Measure your current using a suitable incandescent light bulb brought to maximum bri
Tnx Pete and Marco...yes, I agree that using an RF ammeter to set impedance match, once resonant, is a simple way for those that are without a scopematch. For most LF/MFers however, it is only a matt
Steve & All: One weekend last winter I decided to play around with an Elecraft CP-1 dual directional coupler kit which has 25 and 250 watt power ratings depending on how you build it for 1-30MHz (20
Hi Steve, if you prefer a reliable and accurate inline meter there is a ready to use solution but you have to spend some money. It's the digital vector wattmeter LP100A. http://www.telepostinc.com/ Y
Chris , I have the welz 220 swr bridge , its good down to much less than 1 watt and the calibration is quite close , never pushed more than 20 watts through it , always take it out of cct once the sy
