[Repeater-Builder] Re: Strange Signal on 158.275(ish)
Thanks for the help on this so far all! OK, I get email digests (a lump of messages in 1 email) instead of individual emails for each message. My email client is Hotmail, which I can and do sometimes use Outlook Express. In the emails, there are no attachements to click on to open. When I click on the title of the message, it takes me directly to that message on the Yahoo group. On the group there is a box that says there is an attachment, but nothing is actually attached. It even says the name of the particular file, just no attachment! I'm stumped... Maybe I can try looking at them through Outlook and see if that makes a difference. I even made sure Hotmail was not blocking any inbound attachments, and I can not see any type of filter that would prevent it. Thanks again all for your help!!

While this one is not a huge problem, it happens too. Visitors come to Las Vegas from a lot of foreign countries. People in the UK have whats called PMR radios. It's their FRS service. The radios are all simplex, 8 channels on 6.25Khz splinter channels starting at 446.000 Yep! if you scan those channels here you DO hear activity on them! For the record, most countries in EU have license-free radios in 3 frequency ranges: - LPD (Low Power Device), 10mW, 433.075 - 434.775, 68 channels in 25 kHz raster. Not so polular beacuse 10mW doesn't get far in cities - PMR (Public Mobile Radio), 500 mW, 446.000-446.100, 8 channels in 12.5 kHz raster: 1 446.00625 2 446.01875 3 446.03125 4 446.04375 5 446.05625 6 446.06875 7 446.08125 8 446.09375 These radios generally have PL support.

Hi Geret, I have some friends in Sweden that use something like this, no one seemed to know what freq they were on. When a few of them came here to the US we were talking about this and I showed them my Motorola GM 68, ICOM U16 and GE MPI II and GE PCS radios I have on GMRS. They loved the range of these and wondered if they could use something like this back in Sweden. I looked all over the Internet for information about this and could not find a thing. But now you mention PMR, I am going to focus my research there. Where in the UE are you by the way? Many thanks for all that good info!

Re: [Repeater-Builder] Re: A warning to Land Mobile Radio Dealers
Some try to develop scenarios that justify enabling transmit capability for Public Safety frequencies. An intruder on law enforcement frequencies may be ignored as a false distress call as they begin intruder procedures. As noted before, law enforcement is quite territorial about their communications channel. In Michigan you will not be treated well if your vehicle can transmit on their channel. I witnessed one ham who was pulled over when he was transmitting on amateur radio and the nearby patrol car's scanner had front-end overload. Fortunately, he was able to avoid citations and impound, but was delayed substantially. What will you say when an law enforcement person looks in your vehicle and says, What's that radio? Does it receive or transmit on police frequencies? Mike - AA8K Richard Fletcher wrote: J. C. and the rest. Yes I am going to say this because it seems to have been missed.

Scott, I must agree that the CK1614 is an extremely versatile timer, with many potential uses. However, using it for fan control is not only expensive, but unnecessary. A fan blowing on a transmitter heat sink does absolutely nothing immediately after the transmitter is keyed, since the heat sink is likely at ambient temperature. It takes a period of time for the heat sink to warm up, so operating the fan prematurely is a waste of energy- which may be an issue for a solar-powered repeater. IMHO, the most efficient means of fan control is also the cheapest: A thermal switch. My first choice is a Cantherm #R2005015 normally-open thermostat that closes at 50 degrees Celsius, about 122 degrees Fahrenheit. When attached to a heat-sink fin, it turns the fan on when necessary, and keeps it on until the heat sink cools below about 100 degrees F- around body temperature.

Re: [Repeater-Builder] Neat kit for switching repeater devices
I agree that timers for fans are a waste of time, effort and money. If you can stand a little waste of power, I like to simply key the fan with a relay driven by PTT. Sure, it starts the fan before it's needed, but to me it's no big deal. Once the repeater stops transmitting, so does the source of heat - it won't get hotter, but will cool down slowly on it's own (just like turning the burner of your stove off - the pan starts to cool right away).

[Repeater-Builder] Re: A warning to Land Mobile Radio Dealers
In reality what are the chances of needing to use any frequency that you're unauthorized to use in an emergency? And I am talking like like or death in a car sinking in the river emergency- not you have a flat tire and are stuck in a snow drift emergency. Most of the time one can use a cellphone of some other means rather than using a frequency that they are not licensed for. I bet you if I came up on a police car that had been in an accident and the officer was unconscious, I wouldn't get into a bit of trouble for picking up his radio and calling for help. It isn't any different if someone were to do it for themselves if need be. I'm sure they would investigate it, but I don't see how there would be anything to charge someone with if it is a true emergency. My sense of entitlement comes from that fact that I would use any resources that I have at my disposal to save someones life, and worry about the consequences later. Are you going to follow the speed limit if you are trying to get your loved one to a hospital because she is in labor, or worse yet sick or hurt? NO! We're talking about following rules here and there are always exceptions to the rule. I hope that I don't ever get put into a situation where I have to make those decisions, but I know what I would do.

Re: [Repeater-Builder] Neat kit for switching repeater devices
I agree with Eric's assessment of the NOT running fans when not needed. I do the same thing, slightly differant. I had some left over solid state Waterbed thermostats. i wired them to switch around 109 degrees (they topped out there).I wired them backwards to when the temp got to 109 they switched on a SSR. fans would only start when needed. Saves the life of the fans,filters and cuts down on the dirt inside the cabinet. I am in the process of setting up a few PURC-5000/MSF5000 on 900Mhz and 440Mhz and they all will have this type of fan controller.The PURC has a set of three fans in a rack mount.The heatsinks are MASSIVE in this beast, takes a while for it to get warm.In Normal operation the fans will hardly run, especially if they are in a cold mountaintop site Kirk On Sat, May 1, 2010 at 11:36 AM, Eric Lemmon wb6...@verizon.net wrote: Scott, I must agree that the CK1614 is an extremely versatile timer, with many potential uses.

Re: [Repeater-Builder] Re: A warning to Land Mobile Radio Dealers
I would submit that the FCC has claimed enforcement over radio transmissions in the USA, and that's in the radio is not relevant since it's out of his jurisdiction unless he wants to represent himself as a federal officer. Of course, this is not the proper attitude to present, but it is factually accurate. BTW, since the 80s, the FCC's enforcement has maintained that it's the *end user's* responsibility to ensure licensing, not the programmer's. It's sad to see this interpretation reversing itself, as many times, and as I bet is the case here, the radios were programmed for an entity that has multiple licenses on the frequency in question, and it should not be the programmer's job to interrogate as to *where* the radios will be used. I bet they simply programmed them for Wal*Mart, a licensee, not for that specific store. It should be strictly Wal*Mart's responsibility to ensure that location is licensed properly.

Re: [Repeater-Builder] Neat kit for switching repeater devices
This is excellent Eric. I have an R1225 repeater in a GR500 case. There is a fan but it runs continuously. The duty cycle is low but because of the nature of the service there are times when it may be very high for extended periods of time. So most of the time the fan is not needed, but I want it there for those rare occasions. I don't recognize the part no. on the fan it looks remarkably similar to the one stock in GR500. This will work very well for me. Thanks. lh On Sat, May 1, 2010 at 8:28 PM, Eric Lemmon wb6...@verizon.net wrote: Larry, My first use of this thermal switch was on a solar-powered Motorola R1225 UHF repeater at a commercial site.

RE: [Repeater-Builder] Neat kit for switching repeater devices
Larry, That's odd; both the GR1225 and RKR1225 repeaters I am familiar with, which use the R1225 transceiver, have a small thermal switch that is wedged between two of the heat-sink fins. In both repeaters, the fan runs only when the radio gets hot. I am surprised that you have a repeater using the R1225 in which the fan runs continuously. Perhaps this installation is a prime candidate for a thermal switch! 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Larry Horlick Sent: Saturday, May 01, 2010 7:13 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Neat kit for switching repeater devices This is excellent Eric.
