Cobra 200 Rev 2 Clarifier Range
Guys A friend of mine has a Revision 2 Cobra 200 GTL DX (PCB# PFM-0090A-BE) It's well documented that the coarse clarifier shift isn't sufficient on the Rev 2 to reach the zero's (obviously it needs 5Khz at the very least but only manages approx 3Khz) I'm led to believe there are a number of ways to...

The Skypper is a folded wire yagi and works very well.
Best wire is 'flexweave' multistrand but it's expensive.
Good Luck

No output - final or driver?
Guys, I've got a radio with no RF output (TX into a dummy load showed nothing on the meter - also no signal received on another radio in the same room on same frequency) All other functions work as they should. Am I right thinking that if the finals have gone, I should still get output from the driv...

PA transistor swap - advice needed.
Any advice appreciated guys. Can a 2SC2290 transistor be replaced with a 2SC2879??? I looked at the data sheets for both & the voltages are all identical between Collector/Emitter/Base. The only difference I can see is the collector current is higher (5A more) on the 2879 (the 2290 is 20A) &...

Hi I'm looking to improve the RX section of a EPT690010Z PCB inside the Cobra 148F GTL DX+ I'm not too bothered about the AM/FM modes but I'd like to increase sensitivity of SSB without increasing the noise floor.

As probably stated in the post above (but I couldn't be arsed reading it!) mobile interference is either picked-up via your antenna (radiated) or via your power leads (conducted) - so before you start looking for remedies you need to establish which of the two it is. Plug a dummy load into the ant s...

You don't need a tune-up, just a bigger power supply if you intend to use it home-based. These things draw over 40A on setting #6 (600W PEP) If you're running mobile then make sure you hook that bad-boy directly to the battery (not to your cigarette lighter socket - believe me, some folks do try!!!)...

Mike,
I could use that info you have on the Belcom - my problem is similar to Soundmanjim's but mine corrects itself once the radio has warmed up.
Any info would be greatly appreciated.
