Is it bad to leave my radio on when i crank my car? sometimes it'll display weird behavior, like, it'll go back to scan mode when I previously had it lisening to a specific memory, or vice versa. idk. regardless, it power cycles every time (i'm assuming from voltage drop) does this mean i need a new car battery?

Hook a voltmeter up to your DC cigarette Jack while you crank your engine and watch the voltage… You're just giving it very low voltage and it's chips are losing logic

fwiw my radio is wired directly to the battery. I disconnected the negative battery terminal troubleshooting a broken power seat and the radio was still on. I guess my antenna is grounded well.

[ask] me about the time i got handed a weirdo positive ground cb radio and couldn't figure out why it kept blowing fuses fun facts taht radio was shipped with mods to make it work positive or negative. somebody took the time. it was like cutting traces and flipping diodes and poo poo too, not trivial

i had an azden that would get scrambled from (e.g.) 145.000 to 145.005 when i started the polo (no direct entry so impossible to reset from the keypad), this also wiped the channel memory and i had to do a manual reset by opening the covers and shorting some pins. the battery's probably dropping to like 3-4V during cranking, 2-3V for the +5V internally, below what older ICs can operate with best fix is to get a new radio or car, been driving a few recent model VWs for work lately and they all have really robust electrics with no brownouts during cranking aux battery is also an option, i made a prototype for the polo that would run the radio off a 7Ah SLA and charge when the ignition was on

having read through most of this thread, having passed the tech test on hamstudy with no studying at all (protip: if there's an answer that's longer and stodgier-sounding than the others, it's correct 80% of the time), and now having discovered that there's a walk-in testing session a mile from here when i'm on vacation in a few weeks, i've decided to try for the tech and the general. granted i have no loving clue what I'd do with them, i've only ever bothered with a little mild shortwave fiddling, but how hard can it be. i am nevertheless in awe of both the technical acumen displayed by some of the regulars here, and even more in awe of jonny's ability to live in a loving mobile radio station.

I'll just deal with it probably. charging a small SLA instead of a big deep cycle marine battery is an interesting idea though.

If you're crafty you can just use one big existing body bolt if you got one in there. other than that you need to bond to the car body via a very short and low inductance thing. so you're still looking at drilling a hole or using existing

i had a lot of fun setting this up and im kinda rly proud of how it turned out so here u go... this could all go back to stock easily. assuming i could find the screws to mount the tape deck back on the bracket... it never will tho cause im driving this mofo until the wheels fall off, or gas hits $4/gal i guess i did drill those pop out things but im sure replacements would be easy to find in a junkyard. that onstar is analog btw, lmao.

It's good. The build quality is excellent. Had you done the badgering with this radio instead of the pipe it would have had the same effect, it's that solid. Audio quality is good, much better than the baofeng. It's easier to program too, but that's not really hard to do since the baofeng is SO bad. One feature I miss is being able to monitor two frequencies like with the baofeng. I use that for monitoring my local 2m and 70cm simultaneously. But hey, now I have two radio's so I can monitor THREE frequencies. My main gripe with the thing is the volume knob, which is too small and too close to the antenna for my hamfists. I also did the mod to get the extended TX so I can use it outside 144-146 and 430-440. This'll come in handy when I bring it to Vegas in a week or 2. Barely had it for an hour before I took a soldering iron to it, lol But yeah, very happy so far, thanks for the rec. spankmeister fucked around with this message at 23:33 on Jul 16, 2015 |

They aren't picky with who they talk to and are pretty much just "try it out!" CW evangelists. Nail a QSO, talk to a dude. Then spend a little while just listening to guys chatting at a speed higher than I can copy. to end it out i have a big speed practice where I just get on the code practice oscillator, turn the speed up to about 25 words per minute, load up a couple of tickets in the Jira from work and use the ticket notes as my practice text.
