BAJETON BJ-7800 and BAJETON BJ-8300 are quite similar radios. Both offer excellent value for money and operate almost the same. There are a few differences between the two. First off is the design. Their front faces, keypads and buttons are a little different. The BJ-7800 has a dedicated VFO button, a band button and a button to switch between A/B on the front. It also has an orange trim around two of the side buttons. However, In terms of how they look, I definitely prefer the slightly smaller design and look of the BJ-8300. Both are available with Bluetooth and App programming. And this model, like the 8300, has Super Mode.
Specification: Frequency range: FM: 64MHz-108MHz, Shortwave:2.3MHz-30MHz [has a dedicated HF receive chip], Medium Wave: 520-1710kHz, Long Wave: 153-279kHz, 18-64MHz (Some TX – read below / all RX), 135-520MHz (TX/RX), 18-620MHz (RX/TX), 840-999MHZ (RX) Modes: FM [wide and narrow], SW, MW, LW, AM and SSB. The second antenna on both radios is for listening under 18MHz USB / LSB. Over 1000 channels, Dual Watch function, FM radio, wireless copy, good airband reception, CTCSS / DCS, USB-C charging, Spectrum analyzer, NOAA and scanning features.
Some people have compared this model to the Quansheng TK11. Only the BJ-7800 is considerably cheaper. Reviews for both Bajeton models talked about here are excellent. I think people are really impressed with the sheer amount of features offered.
Transmit Frequency Confusion
Just like the Radtel RT 920 and other similar models, there is some confusion regarding the transmitting frequencies on this radio. Particularly between 18MHz – 64MHz. It can transmit on 27MHz, 29MHz and 6Meters [50mhz], but from reports the power output is very low. And many reviewers / users consider it pointless because the travel range is very limited and the harmonics are very high. Also note: all transmissions are in FM only. It will not transmit in any other mode.
All in all, an excellent radio for the price. But it definitely receives better than it transmits. Especially out of band.
Latest advertisements indicate that it will work on 27 MHz. My initial evaluation shows it transmits FM only.
ACB walkie-talkie seems to verify that fact. Did try it on 29.6 and 52.525 MHz. I will hook it up to an external antenna for more tests.
Thanks for a nice summary on this radio. Can someone verify that it’s the same as UVK – 5 (99)?
Hi Don. Thanks for your comment. Yes, there has been so much confusion regarding the transmitting abilities of this radio and many others. The earlier product descriptions from sellers was wrong for quite a few of these radios.
One that stands out, which has basically the same frequency range as this one [and is almost the same radio overall], is the Radtel RT-920. https://rxradio.net/radtel-rt-920-10-watt-ham-shortwave-2-way-radio/
I covered the frequency confusion a little in that post.
In regards to the Quansheng K5 99. They are fairly similar, but the Quansheng does not go down as low in frequency. The Bajeton can go down to 153KHz and has a dedicated HF receive chip on the motherboard. The newer Quansheng K5-99 starts at 20MHz out the box. The older Quansheng K5’s start at much higher out the box [50MHz].
But with many of the Quanshsheng’s, they are much more modifiable. The Quansheng K5 / K6 range can be modified to transmit on any frequency. But the transmit power isn’t very good out of the specified frequency ranges.
And yes you are correct, they both transmit in FM only.
Kind Regards
I got mine a few weeks ago.
The manual is not too helpful and the Bluetooth app is not very good either.
In the HF section, I have found it transmits in the range 26 to 30 MHz, but even with a 11/10-metre band rubber-duck, power output is very low.
I have not been able to check if it transmits at 50 MHz yet.
But, for just under EUR 25,00 from Banggood, I wasn’t expecting much.
Plenty of time to play around with it, though.
