    JeepCrawler98 got a reaction from dwmitchell61 in Wouxun KG-805G, FCC ID WVTWOUXUN16, and blanket 95E approvals   
    Yeah it looks like the WXVTWOUXUN08 includes the KG805; I assume with KG-805G you mean WXVWOUXUN16 since they've pulled it out separately as you pointed out, but the KG-805 appears to have 95A (prior to the rule change) as well. Both the 08 and 16 application seems to take the same approach of including multiple models. It's my understanding that manufacturers are allowed to revise their radios so long as it's not a major deviation from the original design; at who's discretion is a major deviation made? I suspect it's probably the manufacturer's best judgement, which doesn't necessarily ensure good judgement.
     
    The question always remains is what label comes with it; that's the crux of all these import radios - it can be hard to determine before hand that what you end up with even has any FCC ID imprinted on it somewhere, let alone the one you need; the 16 application lists a lot more models, and they could take the approach that Retevis does on the RT97 repeater where depending on what 'option' you select it comes with a different FCC ID even though the basic radio is model number remains the same. Motorola does this too with some of their radios which often have shared 'marketing' model numbers (I can think of the Radius radios at the moment) the only way to identify what you're getting is to look at the part numbers, but often the FCC ID label is easier. Kenwood on the other hand has a different model number for every radio variant.
     
    I'll see if I can dig up the reddit thread on the WVTWOUXUN08 discussion. Edit: https://www.reddit.com/r/gmrs/comments/e9ytiy/new_wouxun_kg805g_professional_gmrs_radio/

    JeepCrawler98 got a reaction from JLeikhim in Narrow Band for everyone???   
    Modulation or how you use that power does too - narrow-band FM (11.5khz width) vs wideband FM (16Khz width) has by the equivalent of about 6db penalty on SNR when looking at highest modulating freq (2.75khz vs 3.00khz) & peak deviation (3khz vs 5khz) per Carson's rule.

    edit: I see this topic was already heavily discussed in this thread; carry on!

    JeepCrawler98 reacted to JeepCrawler98 in New Interfering (IX) Signals - "Baby Monitors" using GMRS/FRS   
    Can you talk back? I’m sure their users would be perturbed if their monitors started talking back at random times.
     
    Fixed stations are allowed to communicate with other fixed stations at up to 15 watts on the repeater input frequencies if you read the Part 95 rules to a tee - can a parked car be considered a fixed station?
     
    Park a car on both sides of the building and have a conversation with your fixed station buddy about the prevalence of illegal baby monitors on federally regulated GMRS channels. It’s not intentional interference if you’re trying to work around pre-existing interference.
