The last time I heard DSB was from 2 guys who have been SK 35 years or more :) I never expected it to make a comeback, especially for this kind of price. Amazing.

Thanks very much for that, I however would prefer to have a pole so I don't have to hold the beam up. I lift things all day at work, last thing I want to do in my fun time is lift things :)

Great video. Hopefully 2m and 70 SSB can be revived with this mod to such a cheap radio. 2m/70m is pretty dead where I am. Do you have a video for the tape measure 3 ele beam? Just wondering about what kind of matching arrangement you have used. Cheers!

Uses a hairpin match. More: kzfaq.info/get/bejne/e9Ogp7t5tLmvdo0.html

There is an option in the IJV firmware to switch on a pre amplifier. Not sure if it will work on VHF. "Activates the filter change circuit for frequencies after 240 MHz and sets the radio chip to a +9dB increase in reception. Similar to a preamplifier, to be used in exceptional cases of low signal because it can cause distortion in listening, switch it off when not needed."

I think it's intended for satellite operation. Would normally only be useful in a rural area due to RF overload being an issue with these sets.

Very cool. So do you think you could get better range between two HTs in DSB mode vs FM? My guess is that you could get a bit farther due to the lower noise floor with the sidebands.

@vk3ye 11 күн бұрын

Not sure. Maybe in a country area. In an urban area a good band pass filter would really help given these radio's front ends. But CW to CW would definitely be further!

What’s the power output on SSB is it 15pep or 5w like fm mode?

@spakkajack 15 күн бұрын

Hi Peter, the firmware link does not appear to work. McAfee tags it for a start as dangerous, then a 404 error.

@vk3ye 15 күн бұрын

Others and I have ignored it and it works.

How do you enable tx on ssb. It's disabled for me

@vk3ye 15 күн бұрын

Maybe go into the menu setting and check your tx is enabled?

@crazyman1964 15 күн бұрын

Hi Peter, yes I have checked and it appears to be enabled, still no transmitting.

Wonder what you could do with say a lightweight 5 element antenna on a 6m sturdy pole
