How to program VHF channel on Baofeng BF888s UHF radio and will it be useful?

Let us try to answer the question above. How to program VHF channel on Baofeng BF888s UHF radio and will it be useful?. So on the first question, can we program VHF channel on BF888s UHF radio?. Fortunately yes it seems that the radio chip on Baofeng BF888s are capable of accepting VHF frequency channels although I have not open the radio to check the datasheet on what chip was actually used on this tiny radio with a good form factor.

Now that we are sure that the radio can accept both VHF and UHF frequency, let’s move to the second question, will it be useful?. Let’s answer that by watching the how to video and let’s give out the conclusion later on.

So let us now give the conclusion after watching the video playlist. Will it be useful after programming VHF channel on it?. My answer is a YES and NO, yes it will be useful for monitoring radio frequency on VHF channel and no it will not be useful for field work as the measured output power on VHF is less than 1 watt for it to be useful on normal field work. Although I must admit the radio has a good form factor and suitable for short distances communication office or home work.

Building a high gain 2meter 3 Elements Yagi (Video Tutorial)

Tutorial video on building a high performance 3 Elements Yagi for 2 meters VHF radio transceiver. This design is centered on the Philippine amateur frequency band (144-146Mhz VHF) center frequency is 145Mhz with 1:1 SWR. The design and technique used on this video can be adopted on other antenna design for other specific frequency you intend to use. This is the same antenna we are selling on this website (for those who doesn’t have time) you may directly order the antenna on our shop. The antenna is tuned to the published frequency range as specified on the product page however you may still use the antenna on the edge of the band and it will be operational from 143Mhz to 148Mhz.

Materials and measurements

At the end of the video we made some SWR measurements and tuning including propagation testing. The antenna is mounted indoor with camera tripod 1 meter above the ground using Yaesu2900R 2meter rig. The result is a very much acceptable range with almost reciprocal transmit receive (S2 to S3 TX / S3 – S4 RX) with a very good quality audio . From my QTH at Las Piñas (DW1ZWS) to Fairview Quezon City (DU1RFU) is 36kms air distance.

Cheers and thank you for watching everyone!.
