    I got one of these a couple weeks ago through Amazon Vine. I don't have an SA, but everything else I tested really impressed me. I was originally expecting it to be a slightly upgraded Chinese HT, but it definitely has more than the bare basics. I also really liked the noise reduction function. Not sure how much I'll actually use it, but its fun to know that its there.

      @@TheSmokinApe UPDATE: I received and programmed my RA-89 using CHIRP and am extremely pleased with the results. While the UV-5R triggers a 70cm repeater 5 miles away, it does not come close to accessing repeaters 23, 30, or 43 miles away. However, the RA-89 does trigger these repeaters - I am especially impressed with the repeater 43 miles from me. Both tests were conducted using the same magnetic dual-band antenna in my car while sitting in my driveway (my terrain is very hilly with lots of trees). 10 watts is key, and the fact that this is a 'clean' radio (unlike the UV-5R) makes me feel much better about it. Thank you again for your thorough testing and review.

    They must have snatched up all the RF Engineers in China, since others can't seem to get this right. Go Retevis! Thanks for sharing Ape.

    great test . A clean radio puts the power right on the frequency that we want . I bet that HT sounds good on the air. I have a few different Retevis HT and they all check good. I have a 50 DB attenuator 25 watt I use. has N connectors. adapter to SMA and my short piece of RG 316 has N on both sides. my spectrum has N connector. same test . love when you test radios. USB C is standard charge port. even cell phones use it. some with PD for fast charge. waiting for Japan to make USB C . they have one with micro USB. lost of low cost USB solar panels around. some work great and some not so well. the best part of USB C is you just plug in. no up side4 down like the A B micro and mini USB. I have a nano VNA-H4 but not the tina SA. I like my full size spectrum with tracking gen. helps me tune filters and cavity's and duplexers. ETC. 73's

    • @TheSmokinApe

      Hey Robert. I have a full size SA but I typically use the Tiny in the videos so others can learn and play along. USB-C across the board would be great but likely will eat into profits of the big 3 because they like to sell charging cradles. Even if you had to charge directly into the battery it's a plus... Overall, I would say that Retevis is one of the better Chinese vendors. Thanks Bro!

      Thanks Kurt. If they are really bad performers, they often go in the trash or saved for future comparison tests. If they perform well, I will pass them along to new hams, channel supporters or people who are working to get kids into the hobby.

    Is the reciever sensitivity and selectivity on these radios any good? It's hard for me to justify grabbing another handheld when my Icom IC-V80 from Ebay still outclasses every chinese radio I've used so far.

    • @TheSmokinApe

  • @gaptastic
    @gaptastic ปีที่แล้ว

    Yo! Ape! I'm trying to understand why you're using 50db attenuation? Given the radio is 10W maybe more, maybe less. The tiny SA Ultra says to provide less than 10dbm into the device. Being conservative I used an output of 15W and using rapidtables, I get a dbm of 41.8., so in my mind 40 should be good enough, no? Am I missing something? Peace be with you brother Ape!

    • @TheSmokinApe
      @TheSmokinApe  ปีที่แล้ว +1

      Hey Gap, you are correct 10w is 40dbm. In my experience the TinySA is more accurate when you measure lower signals so I tend to be an over attenuator type...

    146.521MHz - 146.52MHz = 1 kHz, not 10kHz
    I am curious what your scope frequency accuracy is. Maybe you should get a good-ish frequency counter to know for sure.
