I have several in the shack for Hi Fi and ham use, I have some old
Realistic (RadioCrack) 10-band equalizers Cat. Co. 31-275 and 31-1989,
and a Sansui GM77, and all of these can be had in good condition for
under $50 on eBay if you shop carefully. New ones by Behringer, or
Technical Pro, or maybe Peavey can be had for around $99 or so.
Sometimes you can use one channel of a stereo model on one rig, and the
other on another rig, allowing for separate EQ of two rigs.
TenTec radios are cool because they sometimes have a LINE-OUT jack on
the rear (typically on the octopus accessory ACC-1 jack cable) and that
allows you to use the rig speaker, or an extension speaker, plus route
the audio at Line-Level to the EQalizer and powered speakers, and even
use the headphone jack separately and still have the audio routed to the
LINE-OUT line level jack (and maybe put your headphones into the final
speaker/headphone device) - or - you can route the speaker out to the EQ
and powered speakers, or the like, and you have some flexibility on
where to put it. I use the LINE-OUT to the EQ and then input that into
a TimeWave DSP 599zx audio filter, and use its separate output to
powered speakers and/or headphones.
AND, you can usually bypass the EQalizer if you like.
Hope this helps... I can do photos, too... just ask.

Which brand of graphic equalizer are you using…I am very hearing impaired…need
plenty of low frequency in audio and have nothing above 1200 hrs.

For substantial selective hearing loss, or for detailed adjustment and
compensation over the useful frequency range, I would consider a multi band
graphic equalizer to tailor the audio to your needs.
The Omni VII, for example, has a limited two band EQ setting, which is adequate
for my needs (I set it on FLAT/0 anyway), but for greater detail and more
specific frequency adjustment, I would probably use a 12, 15 or more band EQ
to compensate the audio. Simple to deploy if you are using amplified speakers
such as computer speakers or the popular small nearfield studio monitors. I
don't use one on ham radio, but my wife and I enjoy listening to old time radio
programs, and we tailor the audio for best presentation of the speech frequency
spectrum, and it makes a substantial difference. She has partial hearing
loss, so it really helps to tune the audio to her limitations.

there is equalization available when pressing the AUDIO button. I have never
played with the settings. Is it possible to contour the audio to a hearing
range?
