I did try turning off the power to the house and it had no effect on the noise floor so I doubt the noise is coming from within my house. I did try several radios (148 gtl, 29 ltd) all with the same results. I’ll keep digging. Thx! 1, that’s the goal 2, not feasible unfortunately 3...

I have a 10/11 meter 5/8 wave ground plane antenna and working DX is incredibly difficult if the incoming station is anything less than a s7. I have so much static and noise coming in. My 2 meter has almost zero noise, I can turn the squelch down completely and its s0 and once in a great while...

It’s alive! I got it back up and running, so happy about that. So what I ended up doing was replacing the other two transistors, so all three of the 2n3904’s were replaced. While I was there, I decided to remelt the solder points of the two replays, all 8 pins on both relays. Once I did that...

I replaced one of the 2n3904 transistors, the one closest to the front controls since a couple of the legs were poorly soldiered to the board. I might as well replace them all just for the sake of making sure they have clean connections and soldier joints. I’ll also look into the relays, good...

Nice to know it holds up over the years! If you've had one since 2009 and it's still rockin' then that's pretty good in my book. Thanks for the confirmation!

@Holydvr Sounds like the same thing happening with mine as well. When you turn the power on, does the power LED and the LED on the far right come on? Maybe @Smokinone can confirm if that is normal for both LED's to be on when unkeyed. The preamp light will come on when the switch is flipped on...

After reviewing the schematic more closely, it is not the same thing as what the Cobra XL 350 I am working with. Some things just don't line up. I ended up finding 3 transistors by the relays, not just the two on the schematic (besides the 2979's) and there are a few other odds and ends that...

Ok, I will order a transistor kit and replace Q2 with the 2N3906 and report back what I find. Thanks for your help!

Not sure if this video would help explain what I mean by it cutting the receive when powered on, but just in case, here it is.

Hi, I recently acquired a Cobra XL 350 and it there are some weird things going on with it. I hooked it up the other day turned it on and I noticed that when I did, the receive on the radio would cut out, regardless of where the pre-amp switch was positioned - almost as if the pre-amp switch has...

Ended up with the Sirio 2016 and, yeah, it works! I'm pleasantly surprised how well it works. Absolutely flat 1.0 SWR across the band right from the start. And it gets out! Very happy with the purchase.

Right on @nbsr, I appreciate the info. I might just have to give the 2016 a shot - it's readily available and seems to have good reports everywhere I look. It's the skeptic in me that holds all the reservations on this thing; but what the hell, I'll give it a shot and if I hate it I can always...

Nice that you still have the v58! I sold mine to a friend and have no idea what happened to it after that. Dang... How do you like the Sirio 2016? If you had to compare it to the Maco, do you feel they perform about the same or is there a clear advantage from one over the other? Being they are...

Lol, for sure! Just hooked up a barefoot radio in my pickup and threw on the Wilson 1000 and made some contacts from SoCal to the east coast… missed that feeling of a successful contact! Good to be back on the air! And yeah, what you’ve said about the antenna is about right. Wow, sticker shock...

Hi, looking to get back into the hobby and looking to pickup a Maco V5/8. Where's the best place to pick one of these up these days? Seems like they're a hit and miss. I had one 20 years ago and absolutely loved that thing. But eventually got out of the hobby as I was gong into High School and...
