[Repeater-Builder] GE Rangr 150 - garbled audio when squelch tones are on
I own 4 GE Rangr 150s. 2 of the 40 watt and 2 of the 110 watt. They transmit and receive beautifully without the Call Guard tones turned on. The deviation is a little low and won't allow me to get full 4.75 kHz deviation, but the audio quality is perfect. When I turn on the Call Guard tone to use a repeater, there is a bunch of noise added to the voice audio. I am thinking that if I have 4 radios doing this, then someone else must have seen this problem before and hopefully has some answers. This radio doesn't have a separate tone board as some evidently do. The tones are created in the CPU and sent to the audio circuitry on the WALSH BIT lines from the CPU. Has anyone seen this before? I have adjusted the deviation pots (one for the PLL, one for the exciter) and still can't get the deviation up to spec. I am getting about 2.75kHz. I have the manual and have studied it thoroughly. My guess here is that I have a failing component such as a capacitor that is reducing my audio. Just wanted to see if anyone else has had this problem with these old radios.

It is deffinately an electrolytic. look for a radial type with a slightly convex top I forget exactly where it is, been a while since I worked on those. When an electrolytic is going bad, or is bad, one sign is the swelling on the top. they usually swell just before they short. Test with a good DVM on the continuity range. it should beep until the cap charges, reversing the leads will make it beep until it discharges. (usually on a value of 4.7uF or more) continous tone means it is shorted. compare time of charge/ discharge to a known good cap or of course use capacitance meter if you have one. look in the discriminator line from the receive through the tone circuit itself. Also seen same with just bad solder joints. --- On Mon, 5/17/10, tec1122000 t...@teccs.biz wrote: From: tec1122000 t...@teccs.biz Subject: [Repeater-Builder] GE Rangr 150 - garbled audio when squelch tones are on To: Repeater-Builder@yahoogroups.com Date: Monday, May 17, 2010, 12:04 PM I own 4 GE Rangr 150s. 2 of the 40 watt and 2 of the 110 watt.

[Repeater-Builder] GE Rangr problem
We are trying to use a UHF GE Rangr that is on packet at the repeater site as a control radio for the repeater also. This is most baffling - having any TNC hooked up to the GE Rangr defeats the decoding of CTCSS used to open the port on the repeater controller! I've tried two KPC-9612s (one + one old) and a PK-96, If the TXA line is connected between the TNC and the radio - no decoding of CTCSS. Otherwise the Rangr works just fine as a packet radio.
Re: [Repeater-Builder] GE Rangr problem
Dave, Bud N0IA has been using a Rangr as a combined packet transceiver and a control receiver for a repeater. Unless you are talking about the same system he was addressing. Last I heard from him I thought it was working. A suggestion - take the packet receive signal from the vol/sq HI output of the Rangr through a 15K series resistor with a 0.22 cap to ground. This will de-emphasize the receive audio for both the TNC and control receiver input on the repeater controller. You may need to add an emitter follower to the output to drive both loads. Also, if you are using pin 34 on the Rangr as the CTCSS decode for the repeater controller be sure to 'lightly' load this pin. It was designed as an input, not an output, and an emitter follower would be prudent to avoid shutting off the audio from the radio. I can whip out a circuit for addressing your installation if you are interested. I have been using Rangr radios as the link to EchoLink repeaters and as a simplex link, and have had really good results from them. 73 - Jim W5ZIT --- On Wed, 7/9/08, Dave [EMAIL PROTECTED] wrote: From: Dave [EMAIL PROTECTED] Subject: [Repeater-Builder] GE Rangr problem To: Repeater-Builder@yahoogroups.com Date: Wednesday, July 9, 2008, 6:45 AM We are trying to use a UHF GE Rangr that is on packet at the repeater site as a control radio for the repeater also.

[Repeater-Builder] GE Rangr
Hi Iam after a control unit socket that fits the plug on the GE Rangr. I know some people solder direct to the pins on the set, but don't want to do this, dosn't look very good.
