 Won't work here.
 We have no legal group per-se who will jump in a scream at the CATV people 
on our behalf.
 Best to let them keep their service and take the TVI from me.

 JE> yeah, right.  Holding yer breath?
 No.
 More complaints from others around me are in the works after the did some 
main trunkline work this past weekened and cut the whole area off-line for 
8-12 hours.

 Same story here.
 There are about 25 Icom IC-706 all-modes floating around localy,many of them 
are parked on 2m FM (one repeater only),some on HF and the rest on 11m!!!
 NONE of these rigs save for maybe two have ever used 6m FM on the repeater 
here,let alone ssb or cw.
 The same can also be said for 2m ssb use and the 706.
 The only time I hear a flood of ssb on 2m,6m and 70cm is when someone says 
the bands are open over a repeater or the contests are running on VHF/UHF.
 Makes me wonder why people would spend $1795 CDN on a multi-mode radio that 
only gets used on 2m FM,HF or 11m and NEVER ON 6m!!

 >> for odd-splits,memories)
 JE> yeah, think there's 5 memories, but it's small in size - definatly a 
mobil
 JE> radio.
 There was an option to make it a base.
 The base-stand option would keep your memories alive from a constant DC 
power source,the extension speaker plugged into the base then the radio,and 
the DC supply was around 10 amps.
 Looked like a mini HF rig with all the options added to it.

 JE> Y'know, I was looking at the back of that rig - it's got a three-pronged
 JE> jack for the input of a T-pad - suppose that's a Tone-pad?  Does the 
audio
 JE> from there go straight to the mixer stage in the IF?
 Yes. The tone pad was external and plugged into the 3 prong circular jack on
the rear panel. The triangular shaped jack was for DC power from the optional
base stand and power supply.
 Not sure how the audio path runs Jeff,mine came with an older Kenwood DTMF 
mic of an FM only mobile for making patches.
 The 6 pin Kenwood microphone plug is the same one that the RCI2950 and Cobra 
series of radios used. You should be able to find it at most any electronics
supply shop or amateur radio dealer.
 >> Nice little rig for a field-day or rover set-up,just

 JE> That's something else I need to get - had a 5w in, 80w out VHF 
mplifier.
 JE> I'd mount that thing in the trunk of the car after modification.
 Diawa and Mirage both make a small 5 watt in 45 watt out amp that will do 
both
FM and SSB with a built in recieve pre-amp.
 The cost for a small amp will be around $100-$150 depending which one you 
et
and what features it has.
 JE> Ultimatly, what I'd like the Mirage 1016B.  10w in, 160 out, FM/CW/SSB
 JE> capable.  One for the house, one for the car.
 GLUTTON! (G!!)
 I have a Diawa model 2180 amp for 2m FM and SSB that takes as little as 1w 
to drive it to full output of 185w. The input can be from 1w up to 45w by way 
of a switchable attenuator on the rear panel to select HT or mobile power 
drive.
 Has a recieve pre-amp for FM or SSB/cw use,and a Hi/Lo power select on the 
front panel.
 High is full out,185w out at 1w to 45w drive and low is 100w out at the same
setting. At 185w out this amp sucks back a healthy 35-40 amps at 13.8 DC to 
keep it toasting along.
 Big enough when fired into a 13 element at 35 feet?
 Plenty for me.
 I did try it mobile once but the car kept stalling out at 185w output,and 
he
dash display went all nuts from the generated RF magnetic field so I keep it 
at home.
