The Alinco DR-135/235/435s also have one, but I don't think the HTs of the same era did. AFAIK none of the Baofeng UV-5R variants or TYT analog HTs have mic gain adjustments either. Bob NO6B

Re: R1225 Ribbon Cable set
Jeremy, ? ?If you cannot find a set of ribbon cables for the R1225 control head, consider using the control head off a GM300 or similar radio instead. The 300's head will work to program and operate the basic repeater channel display, status LED's and speaker if you don't have a control head or ribbon cables to a factory head. I carry a spare GM300 front control head just for the purpose of maintaining R1225 based LTR trunk channels in case I were to need to reprogram or work on one. As a general rule, many shops would never leave control heads on R1225's so there's nothing to be touched and nobody there to look at it under normal operation in a vault room anyways.
Hope this tip helps you out,

Re: Occupied bandwidth - (was Windows 7 config)
Are we becoming TOO TRUSTING??? I remember all these CB shops that would charge people money to build sound effect and noise makers, and rip the modulation limiter out of the radio and tweak the drive and final stages to make 10 Watts (1000 bird watts) by moving the stage from class B to class Crackhead.? More "Bird watts" splatter and harmonics and make the customer sound like an AH so everyone on the band would hunt them down for a Molotov cocktail party or a drive-by shooting.?
I hear the cartels are full encrypted linked trunked systems now, so maybe we have been bypassed.
Oh well, back to building my gigawatt spark gap transmitter.? Cant wait. Kirrrrrch Kik Kirrrrrrch Kik????? Kirrrrch Kirrrrch Kik Kirrrrrrrrrrrrch!!!!

I consider the repeater a repeater for all users, not just those that have the technical ability and knowledge to adjust mic gain and deviation, or speak from the diaphragm and always use proper mic technique. Not to put anyone down, but trying to get users to correct audio issues is a fruitless adventure. I choose to take care of the problem on my end, where I have the ability to do something about it and sleep at night.

Re: Occupied bandwidth - (was Windows 7 config)
I dare say we've been facing a new 'dimension', in the realm of hotspots... many new entrants get (an economical) taste of having their own personal portal to "work the world" with a 5 watt talkie and 10mW - 1 watt (?) IP interface (Skype via radio?)? "This is great, now if only I could get more range..."? ?If we thought $20 import talkies were ugly. take a $5 key fob 'radio', add some LMR-400 and a dual-band j-pole on the roof... plus or minus the variable of where they are programmed.? 'better' on the roof of a multi-story apartment building, office... snuck in the cabinet of a radio site.? Many of course have no clue, no Elmer (or not a good one), no test equipment.
Some of us pushed for the piStar s/w engineers to at least restrict some of the frequency programming to respect satellite, weak signal, etc. but 430-440 is the UHF spectrum for much of the non-US world.? That still leaves ill-defined spectrum there, and a lack of understanding/awareness of band plans, coordination in 440-450.? Who hasn't had a hotspot show up on a repeater input?? "but I'm digital, we don't get interference..." - so can't cause any either?? ?I'm due to help a US-based AllStar hotspot vendor document cautions and mitigation methods so their customers don't screw up too badly.
Surely it was "interesting times" going from AM to SSB, AM to FM, wide to narrow, certainly narrow to narrower. Part 97 is weak on (absent current) tech specs.? Measuring occupied bandwidth is a stretch if not 'impossible' for some of us, but hopefully we can do something to mitigate on-air disaster.? We're the senior experts, well, most of y'all are, some of us are expected to be and we do reach out.? It's good that a lot of us are willing, able and are helping.? Someone helped us, and if not us, who to help new folks not mess things up for us now, and the what the future holds.??
Appreciate y'all for my meager ability to realize how not to mess up the airwaves too much, or for long.

Re: LDG dealer in Canada?
I bought one of the first models in kit form.? Very versatile.? The 100 models are fairly lightweight and easily shipping.? Very low current drain, and has a sleep mode with the relays latched for the last tune.?
The only thing I would suggest is maybe the cable allows you to push the tune button on the radio and drops the power when tuning.? Typically, only a few watts are needed to go through the tuneup and it saves wear and tear on the relays in the tuner and the radio.? I use mine as a remote tuner with a TS2000 mobile and just set the radio to AM with the power set to 5W in AM mode, so tune up is easy.? If the SWR changes when you go to full power, It means something is heating in your tuner or antenna or there is high RF somewhere.? If you can't find a good match in 10 seconds, you need to work on your antenna.
During tuneup, it will be tuning a sequence to arrive at a proper match and will sound like an old engine with loose tappets.? Until the match is found, there may be very high voltages or currents at certain combinations of L and C.? These high voltages and currents may cause weird things to happen to the radio or the tuner circuits and is common with all tuners.? Doing the actual tuning at low power is a good idea for any tuner.
