    CB antenna too close to dual band antenna?

    I'm thinking about installing an 11 meter radio & dual band VHF/UHF radio in my new truck. That'd mean two antennas on the roof. A puck mounted base loaded Sirio P5000 for 11 meters a few inches in front of the high mount rear brake light and an NMO mounted dual band antenna same position but...

    Independent NB/ANL operation on CB/10 Meter radios

    I've never been a big fan of what the Automatic Noise Limiter (ANL) does to receive audio on most CB & 10 meter radios. To me, it seems like it just whacks a lot of high frequencies giving you the illusion of lower noise at the expense of fidelity. Unfortunately, the NB/ANL setup on most CB & 10...

    Negative Peak Compression boards for Cobra 29

    https://www.ebay.com/itm/194062846838 Has anyone ever seen these boards? I wonder if they really do much the jp36 cap/resistor mod can't? I'm a sucker so I bought one to check out.

    Cobra XL-450 Amplifier

    For sale: Cobra XL-450 Amplifier in pretty excellent condition. The only real flaw is fixable. For whatever reason, the previous owner decided the engraved labels for the two SO-239 connectors weren't good enough and had to write their labels with a sharpie on the back of the amplifier. This...

    Crank/Tilt antenna towers?

    I've never had a tower, but am considering purchasing a manufactured crank/tilt tower setup about ~50 ft. tall. The ability to crank it down to minimum height then being able to tilt it over to work on/install/change antennas without having to climb is appealing. What make/models should I be...

    Mix and match connector types on a single piece of coax?

    Any reason you can't have a PL259 and an N connector on the same piece of coax? I recently installed a Collosal 10k in the top of a 90ish ft. tree and used a 150 ft. premade piece of Times Microwave LMR-600 with PL259s preinstalled. I need to cut the excess 50-60 ft. off and put a new connector...

    Texas Star DX1600 from E-bay

    Anyone know if the new Texas Star DX1600s being sold on e-bay are good/legit? I had heard something about fake transistors a while back. I'm OK with HGs, just don't want to pay for some unknown/junk transistors or if I should avoid these latest gen DX1600's all together. This would be for a...

    SunSDRs on AM transmit?

    I know from first-hand experience the Flex & Anan radios work quite well on AM transmit (much better than any modern knobbed HF transceiver) in terms of being able to reach 100% + modulation. Anyone tried one of the SunSDRs? They've got a QRP model 5-8 watts that looks interesting and is under...

    Cobra 29 Channel indicator problem

    So my favorite Cobra 29 has a channel indicator that is acting a little funny. It's an older side mic 29 and when you change to/from (or past?) channel 21 a part of the 2 acts like it wants to go out (it flickers a bit). All other channels 1-40 channel display illumination is solid, including...

    Cobra 29 NW - popping sound in speaker

    I have a fresh out of the box Mfg. in 2017 Cobra 29 LTD Classic Nightwatch. It's a really nice radio for what it is (I've had a lot of 29s over the years, some feel like absolute junk - this one is solid, good knob feel, nice quiet and sensitive receive) My only complaint is this one has a sort...

    Can anyone help me identify this RFI?

    I hear it on all 40 channels CB/11 meters (all channels at once) and most of 10 meters. On 11 meters it's stronger on every third channel it seems. The noise is best described as a high pitch oscillating sound. Sometimes it speeds up, sometimes it slows down. Lately it's been present almost...
