[Elecraft] Mobile high power

[wa2lbi at gmail.com]

They still use 45/46mHz in my area for fire, EMS, and other services but I'm not sure of the power levels.  I've been out of EMS for years.  Years ago in my mobile I ran 100 watts on VHF FM.  In recent years I ran 50W VHF FM and 100W on HF/50mHz SSB w/o issue.Ken WA2LBI LG G6 ------ Original message------From: Jim BrownDate: Mon, May 6, 2019 14:10To: elecraft at mailman.qth.net;Cc: Subject:Re: [Elecraft] Mobile high powerOn 5/6/2019 10:12 AM, Ken Winterling wrote:

Because of the wavelengths involved, RFI coupling into circuitry at HF 
is VERY different from VHF/UHF, which is used by these services. Also, I 
don't know current practice, but when I was doing installs of VHF rigs 
nearly 60 years ago, 25-50 watts was what we were installing. Likewise, 
FM is much more difficult to detect (rectify) than SSB or CW.
