‘bubble pack’ radios are no more defined by their packaging, grade wise, than any of your ‘disposable’ bubble pack pre-paid cellphones sold in the USA.
They are what they are, the cellphones are fairly basic but functional and likewise the bubble pack radios are too.
Anybody who uses range, quality and main argument factors of mainstream non-disposable market kit to rate what are actually disposable short-term targeted devices (the fact they will, with care, have years of solid use doesn’t detract from the fact they are marketed for those who just want a modern equiv of a n-channel CB handheld only VHF/UHF), somewhat misses the point of them.
One of most sentimentally respected radios was one of a pair of ‘bubble pack’ 49mhz handhelds (not the toy looking stuff, ones the size of two PP3’s stacked), single channel (surprisingly, not crystal but synthesized, as the board was common to a more expensive multichannel model too).
You see, what the ‘CB’ fans with their 1/2 channel junk heap equivs didn’t realise that whilst 49mhz was technically LOS operation, given a better overall grade of receiver involved and a notably under-driven PA stage and a higher quality (as necessary for LB VHF upwards) FM RF stages, they were much more consistent at the extremes and didn’t suffer massive break through interference from mobile/base AM CB users running power.
So, and given they ran a decent time on a single pp3 under mixed usage, they were (in the late 70s/early 80s) pretty much what bubble pack radios are today user intended wise, but like like today’s FM counterparts on PMR446, DPMR, DMR, and whatever licensed exempt VHF/UHF service you care to choose, they work and despite being crippled to death, the underpinnings are key and they ain’t as bad as the price point would define them as.
The biggest flaw of them, range wise, these VHF/UHF bubble wrap and retail box preset devices are the forced limitations for their TA certification. Range being an uncomfortable balance between geographical impact on propagation and restricted ERP defined as much by cruddy helical antennas and limited PA stages - but stand in the right place where you can get ■■■■ near EM LOS to the other party and you’ll be surprised how far a few mW’s can go under the right conditions.
So whilst I’d never choose to use a BP sold radio, not when I can buy better quality LE compliant commercial grade kit cheaply enough for occasional group use leisure or otherwise, because of my childhood experience of 49mhz and the not-toy BP radios I used and having a bit of appreciation of how many quality bargains can lie within cheapo cruddy toy/leisure injection moulded cases, if they work as advertised and they’re all that’s to hand, some comms is better than no comms, and if it makes zero difference to you any of they above, if they do the job - use them.
They aint, commercial grade sets by any means, but because of their origins and how they are manufacted to a price point, they share at least a degree of modules (at a basic level) not far detached from cheaper commercial grade kit.
Compared to 80s CB minis and most toy/leisure handhelds, today’s BP stuff are virtually wonderful value and quality.
Oh, and the 49mhz sets I owned - still good and functional even 40-odd years later, just have a better power source than pp3’s and kept on residual charging for emergency. So never underestimate what ‘cheapo’ kit can transpire to be, just buy knowing the score before you hand over cash - it’s a lottery gamble, but compared to 80s gen counterparts, it’s like having a half-good poker hand from the initial deal.
