I've been reading the responses to my own thread on here and watching several YouTube videos and still feel like I do not have a good handle on the attenuation required.??
In the videos, I have seen multiple hams use a 40db 10w attenuator with no internal attenuation to test?a 5w HT with apparently no ill effects.? ?I've also seen some use more attenuation for lower power outputs.? ?To my understanding from reading what has been written here and these videos:
1. I would need around 60-80db of attenuation to safely input a 1w signal into the Ultra.?
2. I should not use the internal attenuator - or, alternatively, I should.?
3. I should use a variable attenuator in conjunction with the 40db attenuator, or I should just use 2 40db attenuators, or I should use the 40db attenuator plus the internal on "auto".?
4. I should use a CleanRF.com RF-S2K & dummy load with a 40W attenuator or by itself (but the CleanRF is only specced?for 3-30Mhz, so I don't understand how it would work anyway...)
I could really use some authoritative answers on how to safely test VHF/UHF/HF rigs without letting the smoke out of the Ultra.? ?I have the 40db attenuator (10w, covers the spectrum) already. I'm not sure what else I need to obtain.
