Hi my name is Will put together ubitx radio kit .Found the audio very low .can ?you?suggest an add on amp .also bought uv meter kit along with made up board? and leads as recommended by F6HOY.the problem .I have no idea how to connect to the main board of the radio.can any one help 73?Will
 

There are add-on amps but as a stopgap measure,
to use the radio until an amp is built and added, just
use an amplified computer speaker. I use one and
am satisfied to use just one channel. Has to be a
stereo set though or you short out one channel of
the rig's amplifier circuit for example if you plug in a
mono plug.

The computer speaker I use is turned up full volume
and all audio control is with the rig's control. Try it
to see if it's enough. Others here will no doubt give
you a website where you can either buy or build an
amp that can be installed inside the radio.

I picked up 5 of these for $8. Just take take the output from the wiper of the volume pot and feed it. works great.

Hi Will,

There are several replies with good solutions for you. You can also use a set earphones and find that you will have to turn the volume down with those. I have been using "cans" for well over 60 years so I can hear my radio and not "annoy" everybody else in the house. CW is music to only a few of us:) I have also just plugged in the computer external amplifier/speaker sets and those work fine.

I can't help you with the uv meter (an S-meter I presume). S-meters are not needed and I have several radios with no S-meter nor AGC. Others here can help you with that.

73,

I took a used computer speaker apart and removed the amplifier. Stripped off the switch, volume control, and plug in ports. Mounted it in the case with a couple of standoffs and bolts.Ran the output of the v4 into the input of the amp. I bought the v4 used with an indian case. The volume control was biased with equal 4.7 k resisters The power comes from the main switch of the radio.

Good idea. Those amps are usually pretty small. Most
I have seen are on a board about 2-in square.
