As commented elsewhere, it should be 50 ohm.Andy1845c said:I am confused on what the 50hm: resistor should read with an ohm meter.
Yes the resistor could be bad,Andy1845c said:I know, that sounds stupid, but it reads 77.1hm: on mine....so I suspect the 50 hm: resistor could be bad.
Quick answer - yes 50 ohm is just the resistor.Andy1845c said:I am struggling to understand impedance. The can reads 50hm: impedance. That dosn't simply come from the 50 hm: resistor, does it?
I'll take a look right now...Russlk said:I have a Radio Shack Cantenna, it measures 51 ohms. It would be worthwhile to look inside to see if there is a bad connection, or the resistor may be cracked.
Sceadwian said:Have you tried to test it under any substantial load? The can says this thing is rated at 1kw, testing the resistance on a meter is completly pointless as the load is so low. Who knows, maybe the 70ohms means the resistor leads are actually dead shorted in the oil bath and the resistance is coming from the burned off resistor material? Testing it under load will show you pretty well what's gonig on with it.

Andy1845c said:Nigel - I've never used a dummy load before, but every ham I have talked to says I will want one. As I understand, it is hooked up in place of the antenna and allows for tuning of the transmitter without going on the air. Learning how to use it will be my next step, but I figure I need to have it working right if I expect to get any kind of accuracy when I do use it. I got my radio (Tempo One Transceiver) a long time ago, and I have never tried the transmitting side of it. I've sure it is way out of adjustment.
