If you can get a patch cable made up that goes from the 4 pin mike jack on
the radio, and splits out into one female XLR jack for audio, and a pigtail
or female quarterinch/eighth inch jack for the PTT switch, then you can run
any sort of outboard audio gear you want using xlr connections.
You can get say an Art microphone/instrument preamp with a 12ax7 tube in it
for around 50 bucks from your local yorkville equipment retailer, like Long
and McQuade.
That said, the older tube radios usually have plenty of preamp gain for the
microphone input so an external preamp isn't necesary...unless you get a
preamp with some tone controls or an equalizer built in...which might cost
you 75 bucks lol.
The reason devices like the W2IHY equalizer box is so popular is because he
uses isolation transformers and ferrite filters to eliminate RF interference
in the audio signal path...something you can usually eliminate by proper
rf/electrical grounding of the radio and any outboard audio stuff...
So yeah, you could mess around with that stuff if you get a cable with a
female xlr jack for the audio input of the rig.
I haven't played HF in such a long time, but I have an art tube preamp and
another behringer tube preamp sitting around that I should hook up to the
old TS830s one of these days and see how they work with the shure SM58.
I've also got a pro audio gator rack with a couple dual 31 band EQ's and a
compressor/limiter/gate and a spare 6 channel mixer that I could throw on
the HF rig for fun haha.
Either that, or get around to sending the ts2000 out to california for
repares and get that back on the air so I can play radio again with
something younger than me lol.
Lots of projects, not enough time...as always.

Subject: Apex 850
I'm really hoping the Apex 850 I picked up a couple of weeks ago works,
despite the fellow who took a look at it messed around with mic it self
plus the 30 dollar cable purchased from a guy who makes and sells them from
Ontario.
I dunno why he had to mess around with the mic, cable ok but not the mic. I
tried it out in the store with everything set to flat on the mixer and I
really enjoyed the sound in the headphones I was waring. Total cost of the
stand, gooseneck boom arm, connecting cable and mic was 100. I had a foot
switch already but if had to buy 1 new, call it 50 bucks. Sounded way
better than my Heil Pro Micro duel for the same cost of 150 and probably
sounds as good as the HM-12 or even the more expensive 2 or 300 dollar
pieces.
I may even just start over and throw this in the junk box and go get
another and have someone else look at the cable I liked the sound of this
apex so much. Apparently if you bump it now, you get a little feed back
etc. I haven't used it yet, picking it up this saturday. Colin, can you
describe this mic to preamp setup? Is it something that I could get going
on my own?
I don't have enough sight to dig around with cable rewiring but I guess any
compitent music tech in a music store should be able to help if I show the
pin out of my FT-102 mic input jack.
