The should be the ubiquitous budget beginner radio. Yeah, it's QRP, but you really can't beat it for the price.

Cheaper than most all of the other QRP rigs out there. My first HF radio was the 817nd, would have been nice for a cheaper option to be on the market at the time.
We shall see if it's crap or not though. |

Did the price drop some to include the case in that $159?
If so, me and my v5 are bummed out. LOL |

Is $199.00 with the case, they refer to it as 'the full kit'.

That's pretty neat.
Could you mount this in something like an ammo can along with a battery and have a self contained portable radio? |

Looking at that uBitx site it indicates they are using Nextion HMI displays. I'm curious how they manage to do that. With the 4.3 and 5.0 inch displays I've used they all emit ungodly amounts of RF. They will absolutely jam any GPS module placed within a foot. They can swamp a the 2 meter band from feet away.
I can't figure out how to mitigate the noise and it has cost me hundreds of dollars and countless hours in a now failed protect design because of it. |

I appreciate the display upgrade for general use, but was actually kind of disappointed that the V5 disappeared without notice, I had a neat idea working for a case and configuration using a larger size LCD, and just hadn't gotten it ordered yet. Pic would have appreciated the build if it actually went together the way I'd thought. |

I will try that! What frequency range are you trying to attenuate? 31 performs better than 43 and covers a larger frequency range as well. If you're using wire that small, and can fit it in your product, a smaller diameter but longer torroid gives MUCH more attenuation. |

If you're using wire that small, and can fit it in your product, a smaller diameter but longer torroid gives MUCH more attenuation. That's part of the issue, I don't really know, 88-200 for sure but it's also swamping L band 1545 GPS. I'm unsure if it's actually causing an issue at L band or saturating the receiver with enough out of band energy to desense it. I tried looking with an Airspy and the spectrum spy app from 25-1700 MHz. I see massive energy across VHF ham/lmr, some up at uhf and a bit at 1545 but nothing that looks terrible there. I did try a 10 MH and 47 uH inductor I had from an old DSL line filter. It helped a bit at VHF but GPS is still jammed. Sorry to hijack the topic. This is just driving me nuts. I'm start a new topic here on it. |

I'm start a new topic here on it. I would definitely try a 31 mix ferrite. Probably grab a 61 also to test, 61 would probably do better at the highest freqs but 31 is really good stuff. Fair Rite 2631480002 or 2631250202 would be the part numbers to take a look at, if you have room to fit that form factor in your design. 2631480102 is smaller and would still give you pretty good attenuation with several wraps. I've seen a few ferrites that I recovered from cables and the like that have really good performance in the 75~200 range but I can't find what mix/manufacturer they are. |

India's lockdown is gonna run at least through the 17th.

They're now rolling DHL shipping charges into the selling price - so for a $10 price increase, you get "free" DHL shipping.

While I appreciate the functionality of the big color screen, I wish there was still an option for the smaller text-only LCD screen for smaller size / lower power builds.
