I would not own a CB without SSB... it's just great to sit back and relax and be able to talk all across the country....
I have a few friends that live 20 to 30 miles away and we can talk to each other on SSB.
with that said.....
I know you don't have a lot of room in there.... if you just wanted to experiment for a while with a small cheap CB to see if you enjoy it....
( hard to get conversations or anyone to talk on regular CB anymore.... great if you and the family or friends all have AM CB's ... but if it's just you I would insist on SSB)
but if you could get by with a normal AM/FM CB.... and I know you have the Cobra 29.... but I would put the Cobra 29 on the shelf for now....... I would suggest spending $94.00 and getting the Radioddity CS-47
Radioddity CS-47 it is the size of a pack of cigarettes and all the controls are on the mic..... so all you have to do is place the body between the seat and the console and you will not even see it!!! and then hang the mic anyplace on your dash... just two small screws for the mic holder and you're done... all the controls are on the mic... it has the speaker... channel buttons volume squelch and every thing in the palm of your hand... it is also modifiable meaning it puts out 8 watts on AM and 15 watts on FM !!!! with a simple modification ( just move a jumper) it also has hundreds of other channels ( but you would need a ham license to use them ) so that would be a QUICK and SIMPLY install
this radio has the "NRC" Noise Reduction Control Technology ... it is a total game changer.. it gets rid of a lot of the background noise and will allow you to hear people that are far away that you would not normally hear because of the background noise... with the background noise cleaned up and less background noise you can talk to people that have weak systems that you could NEVER hear without the NRC....
to make it a little more simple.. if you hear nothing but static and your signal meter shows noise up to say S7 ( signal strength 7 on your meter) and someone with a cheap CB is 10 miles away... well you will not hear him as all you can hear is the static... the NRC allows you to get rid of a lot of the static and now you can hear that person... a weaker radio, far away.... will not be able to talk above all the background noise... so you NEVER want to buy any radio without NRC.... and the CS-47 has it!!!!
and you can then mount a GOOD magnetic antenna on the roof... so "IF" you get out of the hobby, you can just remove it..... if you get a magnetic antenna get one at least 5 feet tall.... a Wilson 1000 or Stryker SAR-10 .... the top of the line they say is the Sirio 5000 Performer... but it's TALL! 77 inches so it will hit a lot of tree branches be forewarned .... but if you're not a tree hugger it would be the best... I use a Tram 3500 that is only 57 inches tall... and it works ok for me.. the others will be better but my Tram is cheaper and shorter and works for me.
the smaller the radio the worse the receive is in my opinion... but normal CB is only for short range anyway so I think the little radio would be fine within 12 miles... I took one out and got 9 miles with it.... not bad... but not great either! for what it is.. it is pretty damn cool and will be a great start to the hobby to see how you like it.
if you mount it between the seat and console... DO NOT BLOCK the thing that looks like a speaker... it is not a speaker it lets air in.. this is a VERY HIGH POWERED radio... it has huge heat sinks on the bottom to dissipate the heat... so don't block it... use the radio bracket that will allow it to stand off the console and allow air to flow
take a look at this video... you might like it? ... he does the whole video and does a good job... but then at the end finds out how to modify it and comes back and shows more of what an awesome radio it is.
good luck on whatever you do.
this is me ( TERRIBLE VIDEO.... DON"T WATCH IT)
