    Loudest Export radio out today?

    4600 Turbo, Wow, that is a lot of power! Your radio has the same main board as my favorite export - the SuperStar 3900 gold (EPT3600-14C). I've got two of those, and wouldn't get rid of them for just about anything, I'll bet your radio really screams with the four SD1446s in it! Man...

    Why All The Concern About "Swing?"

    Hi Davegrantsr, That's pretty much how I run my stuff, too. Never had any real complaints at all. Lots of folks I talk to on CB say "you sound as clear as a telephone call and I have you 30 over, but you ain't got no swing." I usually comment "but I do sound good, though?" To which they...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Hi Switch Kit, "I personally wouldn't deal with noise for very long , I find it to be very nerve racking and would work on giving me a headach most of the time." I hear you! I hate noise, too. That's why I like to modify CB receivers for better performance. :D "I think it's great...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Loosecannon, Thanks for the information on the books - I'm going to pick them up, soon! The ANL diode is a 1S2075. I wasn't sure if the Schottky was compatable or would do any good, but I figured it wouldn't hurt to try it. So, I did, and the results were fantastic! It is D7 in my Uniden...

    Why All The Concern About "Swing?"

    Heh, heh... good deal! It does look cool to watch the needle on the meter swing out with modulation and it is nice to be really loud! If that is what you like to do more power to you! I used to have a JB 150 driving a JB 2000, and liked to key 20 and swing up to 1000 or so. Got the "worked...

    Why All The Concern About "Swing?"

    Ever since I was a kid, I've noticed that most CBers are concerned about how much swing an amplifier or radio shows on a wattmeter. Why? You never see an AM broadcast station doing 50 watts carrier and swinging 50,000 for example... Why not just figure out how much power a device (tube...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    I got in some Schottky diodes from Mouser this evening, and replaced the AM detector diode, NB diodes, and ANL diode - WOW, what a difference that made! My S9+ line noise is now S1 with the NB on! I guess that is what the radio needed. The AM audio seems to have a "smoother" sound to it as do...

    Citizen Band: 11 Meter: Clubs and Organizations

    Do any of y'all remember the North American Outlaw group from the early 80's? I was NAO 661 (I think - it's been a long time...)

    Progress on Tower & I-10K ....UPDATE: It's up!!

    What I meant was that compared to my tower installation and the one at the local police and fire department, etc. , this one is much more professional. I can tell a lot of hard work and planning went into it, and I would be proud to have such a set-up at my 20. Again, great job!

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Loosecannon, Man, I wish I had kept my copy of the "CB Hackers Guide," now! I'm gonna have to pick up a new copy next time I run up on a good deal. I've got a bunch of Schottky diodes and 2SC2999 transistors on the way to me from Westgate and Mouser. When they get in, I'll definitely...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Thanks for the responses - I always like to learn about the point of view that others have. Yep, the Uniden definitely can't compare to a Furuno. I really love the Furuno, and that is what I use on HF most of the time. It does have IF level DSP processing, and will knock out just about any...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Hi Loosecannon, Thanks for the advice! I tried the adjustment a few days ago, and couldn't tell any difference. I'm gonna order a service manual from Uniden and troubleshoot the noiseblanker section. Maybe one of the transistors is bad or something.... :? Oh well, I'll sit it on the shelf...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    Switchkit, The "hair dryer test" is valid to see how well a noise blanker works. Noise blankers are supposed to cut out pulse interference from such sources. That is what they are designed to do; they turn off the receiver momentarily when pulse interference is detected. If they don't, you...

    Maco 200

    I had one of these back in the 80s. It was a good amplifier. I think that it used four 8950s. I ran mine at about 75 watts carrier. On SSB, it was good for about 300 "true/bird" pep watts. It would be at least 29 years old by now, so I would plan on replacing all of the electrolytic...

    Uniden PC 78XL (same as Cobra 29) Noise Blanker Problem

    I have a Uniden PC 78XL, and the ANL works extremely well. However, the NB doesn’t do anything at all. At first, I thought that it just wasn’t very effective. However, after testing it with the “hair drier running next to the antenna method ala Lou Franklin’s advice,” I’ve determined that it...

    Cobra 139XLR ANL- ANL/NB Switch Wiring Hook-Up Help Needed

    Hi Pathfinder 259, You can get the schottkys from Mouser electronics without a tax number. They are about .18 each if you by 500 or more at a time; a little more if you buy less. If you only want to do a couple of radios, you can get “receive kits” from various folks on Ebay. These come...

    Cobra 139XLR ANL- ANL/NB Switch Wiring Hook-Up Help Needed

    Loosecannon, I really enjoy the old Uniden chassis units, and don’t mind putting some work, time, and $ into them. They are definitely worth it in my opinion! I sure wish Uniden still made SSB units. However, since they don't, I try to save all that I can! I got the crystals from Ken’s...
