I have the he 1 and they all come with the battery holder like that. I use an i
pod powered speaker with mine. Audio is a actor of phones. Try several as some
of mine are very loud. Would like to change knobs. Solid little radio.

Subject: [TenTec] Ten Tec model R4020 arrived. First impressions
Hello Gang!
The R4020 I ordered at dayton arrived yesterday. I was unable to get it fired
up last night, but you know what they say about first impressions.
For a brand new radio, the packaging looked like it was used. The bubble wrap
bag the radio came in was all popped. I know this is a mute point, but there
was no 'wow' from me when I opened the box.
I should have read the instructions first, for when I picked up the radio, it
rattled like it had loose parts inside. As a matter of fact, it really did have
loose parts inside—the battery holders, plug and rubber feet.
Number one nit to pick! Those radio shack knobs have got to go!
In keeping with Ten Tec tradition, the AF gain knob was smashed down onto the
front panel. A quick fix with a small screwdriver. The knob wiggles back and
forth now on the control shaft.
Popping the case, only two screws hold it together, the pcb is silk screened
and appears to be of decent quality. Although the pcb is stuffed with surface
mount parts, they are the larger 1206 types and although still quite small, joe
ham could repair this radio. HB-1A5 is silk screened in one corner.
There are provisions for installing 8- AA batteries, basically two plastic four
AA battery holders. You solder the wires together and then to a supplied plug
that plugs into the pcb assembly.
The instructions are six single sided sheets. There's a schematic, but no parts
location overlay. The pcb silk screen is readable so, in a pinch you could in
fact locate a suspect part by the screen alone.
Other than the fact the radio uses a DDS vfo, the radio is quite basic. NE602
mixers are used and a classic LM386 is the output for the audio chain.
Speaking of audio, it's mentioned several times in the manual you MUST use
stereo head phones. DO NOT use a mono plug in the audio output jack. There is
NO internal speaker.
I'll get some power and an antenna hooked up to is shortly....as soon as I can
locate some better knobs!
