148F GTL is unique because it came stock with a built in frequency
It basically is a Cobra 148 with the Frequency Counter and some push
buttons instead of the standard switches.
The frequency counter is only a 5 digit counter.

This radio is modifiable for extra channels - the one I had bought covered
from 26.xxx to 29.xxx . If you wanted a Cobra 148 with extra channels the
148F is nice because the frequency counter always lets you know where you
Many people do the extra channel controls using the NB and ANL buttons,
pushing one of the other or using a combo of them in their on/off
positions can control the channels, this is a nice way to wire the extra
channels if you aren't going to need the NB or ANL features in your setup.
The radio I had also had talkback installed, someone just installed the
resistor across the PA/Ext sp jack - it sounded pretty good.
The Cobra 148 F tunes up very well and has loud audio, my radio swung to
22 watts on AM with crazy loud audio on the stock cobra coffin style
microphone. SSB was equally as impressive. The one I bought had been
peaked for maximum power and modulation. The Clarifier was also unlocked
on my radio.
The bad part was that because the radio was pushing so many watts it would
get hot very easily. The back of the radio got very hot with only 30 mins
of use. Probably not a good thing for long term use as the heat will
eventually cause the radio undue wear on other parts. Although, the radio
was a good 10 years old when I bought it so I guess it's been able to
survive that long.
I made a good number of contacts on this radio on AM and SSB barefoot, the
audio was excellent. The receive wasn't as good as my Cobra 146 GTL or my
Magnum Omegaforce, but it was better than a lot of other SSB radios I've
I sold the radio because it was in a little rough condition and I didn't
like the overheating while DXing. The overheating probably only was
occurring due to the high output of my particular radio, I would doubt
that it was a problem with all 148F models.
This radio is not to be confused with the COBRA 148 F GTL DX. That radio
was an export radio as it had extra frequencies and FM straight from the
