Not enough groundplane. You need to bond the ladder to the RV body with some good quality ground straps. You could also cut a couple of wires 8 feet long and just run them out from the grounded base of the antenna across the roof of the RV. Doesn't really matter how you tie them...
Anytone is really the only game in town worth considering when it comes to radios. They are also sold as Radioddity, and the newest Stryker radios are also Anytone on the inside. I'm a huge fan of the Anytone 5555N2, which has largely replaced my Cobra 148GTL as my go-to radio. Outstanding...
I heard JJ booming in all alone on channel 37 up here around noon today, talking to a station in Texas I could just barely hear. No luck making the return trip though...... I called a few times but couldn't get through the wall of high powered Texans LOL!
Glad I wasn't the only one! Now it's wall to wall Brazilian stations up here...... Impressive signal strengths on some of them.....like S9+. Pretty wild.
No. 10 Amps is not enough. 10 A @ 13.8 VDC is only 138 watts. An 80 watt radio requires at least 150 to 160 watts DC. So it's close, but I wouldn't run with less than a 15 Amp supply otherwise there will be distortion on the audio peaks.
Not understanding why you aren't getting audio from...
Amazing conditions up here this afternoon. I had the radio on 555 USB for just over an hour around 4pm PST while I was working in the shop and along with tons of US and Canadian stations I heard South Africa, including a mobile in Johannesburg, Phillipines, Indonesia, Martinique, Jamaica...
I think you may be onto something there doffo! Up here we have hot dry summers and then the infamous Canadian winter cold. Temperature extremes are never very good for electronics...........
You did the right thing! The displays are notorious for failing. Everyone I know that bought one of those had the display fail within two years.
On top of that, it's just a 40 channel, 4 & 12 watt radio. They sound pretty good on air but beyond that.......meh.
It's almost certainly supposed to be 5 volts. Not sure why super lids reading is so high..... voltage regulation must not be very good.
edit: never mind I see JJ figured it out.
We had spectacular conditions up here until a couple of days ago, and then the latest solar eruption hit and today and yesterday we had nothing...
That's 11 meters for you! One day your talking to the other side of the world and the next there's nothing LOL!
Hey Tin Can I did that on mine too (made the values all 0's) and it made it swing a fair bit more on AM mode. However, I don't think it has anything to do with NPC, I think it more likely that those two menu items (19 & 20) are ALC adjustments.
I strongly recommend posting with a much more specific thread title! There are umpteen threads on here about the 5555N2 already and no way to distinguish yours from all of those.
You will get way more eyes on your post if you give it a more specific title.......
I've never heard of an NPC mod...
That whole style of radio is outdated technology now. The days of buying radios and then having to mod them or do the dreaded "peak and tune" are over. Technology has improved dramatically since those days!
The better plan would have been to buy one of the Anytone or Radioddity radios such...
That's generally option one for me. I rarely sit on 385, 425 or 555 anymore...... seems like every jerk with a radio in the USA is on one or the other of those channels.
In the last two days I've heard preachers, crying babies, air raid sirens, morse code, right wing politics galore, fox news...
It's been going for two days straight right on the international call frequency. Sounds much like an old school over the horizon radar........almost but not quite like the old Russian "woodpecker" that was on shortwave forever.
There are several clues that it is a jammer and not a real radar...
