With the
BPF mounted in the case behind the tuner.
Prior to purchase of an integrated NRC radio this setup (with DSP speaker) was tops in mobile in my experience.
Take the BPF in/out, the change was notable.
“Notable” in that I prefer to run gear wide open (max RF Gain & no SQ).
Warnings can be faint and distant with vehicles rapidly receding away into the distance.
“Faintest signal capture while mobile”, affects my welfare:
maximize income potential while keeping injury/death risk lower.
Mobile antenna on a plastic fleet tractor is sort of ongoing, but most hard limits (location & height & design) are hit early.
BPF &
Tuner are
above & beyond what I figure most operators desire in expense and install problems.
This radio carrier rides on the passenger seat.
With carrier into which to mount all the gear it’s over $500 past the radio itself.
Then additional cabling, etc.
But , by itself, the 411cb isn’t large and adds but one jumper past the radio.
The smarter mobile operators insist on a rooftop permanent mount antenna for their personal vehicle. Where the BPF then does become more of an iffy expense.
Use your mobile rig “as is” for significant hours in mobile would be the test. Day, night,
Skip, etc.
Know what to expect as conditions change (know what those are via experience).
It’s not a “fix”, in this use. It’s a marginal gain.
— If faintest CB Radio signal capture running wide open —
or close to it — is desirable
all day, I vote in its favor as experiment (after an NRC radio acquired or outboard DSP device installed) the idea being to reduce the workload on the receiver.
Do all else in performance maximization first.
— Passing, or being passed by other vehicles with hellacious RFI is part of this (and where the new integrated NRC radios really shine).
