Product Review of TYT TH-UV88
Written by Paul, AD7I
The TYT TH-UV88 a dual band an- alog handheld FM transceiver that I found on Ama- zon Prime for $35 delivered. The contents of the box included the radio, rub- ber flex antenna, 7.4V 1400 mA/hr (rated) Lithium ion battery
and a USB programming cable.
I bought this particular HT because it claimed it included an internal two-tone paging de- coder (like that used by volunteer fire depart- ments in our area). I didn’t expect much and if the paging decoder didn’t work I planned to return the radio to Amazon.
What I found when I opened the box was a radio that had a solid feel to it,
much much better than the typical Baofeng. It felt like my Yaesu FT-60,
The front panel LCD can display the frequen- cy or an alphanumeric name of up to 10 char- acters (like “AsburyPark”) and shows both the primary and secondary frequency at the same time. The radio is programmable on the PC with TYTs software as well as CHIRP. Neither program is like RT Systems, but be- tween the two programs one can configure most all the features. Many features can also be controlled from the front panel.
My primary dislike about the radio is that it doesn’t have a channel selector knob and doesn’t have a knob for squelch. The user se- lects memory channels by pressing the UP or DOWN buttons on the keypad. Not bad if you only use eight to ten channels, not so good if you have 70 memories programmed. There is no auto-repeat if you hold the UP or DOWN button active for an extended time. As for no squelch knob, in the commercial world most all analog radio systems are operated with CTCSS (PL) required so a noise squelch isn’t all that important, but noise squelch remains necessary for ham operation.
I don’t know about receiver sensitivity and I don’t know how bad the harmonics are from the transmitter. Harmonic radiation is a problem for most Baofeng mod- els and it’s not clear if TYT invested in decent harmonic TX filtering for this radio. The Amazon product listing says that the radio is “FCC Certified”. That certification is only for Part 15, not Part 97, and means only that the receiver’s local oscil- lator does not leak above limits, the same requirement as for a $7 AM transistor radio. Another dislike for the radio is a lack of DC power in- put jack. DC battery eliminators are
available so that’s an alternative.
But what I do like about the radio is that it has a good solid feel to it, that the

my personal gold standard for ham analog HTs.
In operation I found that I had to set the TH-UV88 mic gain to high (low, medium and high are the possible values) and after doing so got good audio signal reports. The audio from the radio’s inter- nal speaker was loud, clear and without much distortion (although I’m hearing impaired so you would need to judge for yourself). The re- ceiver seems to hear what my FT- 60 hears, but I don’t have a service monitor on which to test the receiv- er sensitively on the ham bands and outside the ham bands. Transmit- ted power is a solid 2 watts, not the 5 watts claimed.
