I went to that place once decades ago. Wow, what a place. Huge warehouse sized spaces with racks of gear, almost as far as the eye could see.

Thanks for reminding me.

When I first came on here I read that MURS 151.88 DPL 143 was the "official" freq. I've had it programmed ever since, just in case . . .

Why would it be? If the seller chooses to take the 3% hit himself, why should Paypal care? If I sell you something for $100, paypal is going to want $3. So instead of making $100 on the deal, I would only make $97. At the end of the deal, Paypal is still getting every penny they would be entitled t...

I sent an email to Bomar, but didn't get a response. I'll try International next. Forget Bomar. Their stuff is not known for high quality. ICM is the only way to go. Lifetime warranty too. All you need to tell them is what equipment you have and what receive and transmit frequencies you want. They ...

I got one of them on ebay a few years ago for $6. Will is right and it is as far as I can tell absolutely indestructible.

wa2zdy

using the same class of radio and antenna? Yes.

The only thiing about a business license, and that includes the dot freqs and even 151.625, you need to be a business. 151.625 is chaos wherever you go, so while you could get away with using it, it might be too crowded. If those were UHF radios, GMRS would be the way to go. REAL radios work fine th...

Gamber Johnson has always been quality stuff. I first used one of their slidemounts 30 years ago. The antenna connector arrangement was pure genius!

wa2zdy

Yep, typing that stuff in from a list and double checking to avoiding mistakes is tedious at best. You wouldn't enjoy doing it.

wa2zdy

You said no mic. That's why. The hangup button can't be grounded if it's not there.

wa2zdy

Ahhhhhhhhhhh fond memories, thanks!

wa2zdy

To power that 110w radio you'll need a 35A supply. The radio probably draws 26-28A while transmitting (my Syntor X draws 28A) and you need some headroom, so a 30A will not be adequate. The supply shown in the photo is not big enough. I can tell that just by looking at the connector that uses only tw...

I sure am looking forward to seeing that pic. When I was a tyke in the mid 1960's my mother was a cab driver and my grandmother was a dispatcher for the same company. That BY station was sitting there hogging up the whole darn desk!

Memories . . .

I've done this with the Genesis MVA. It's a pain. Pray, pry and keep your fingertips out of the way.

wa2zdy

All BS aside, you can probably get it done by a local trophy shop. I've had it done that way with no complaints.

wa2zdy

And switching the toggle to "monitor" only sets the receiver to CSQ, it does not unmute the audio. The monitor button on the side SHOULD unmute when pressed and if held a few seconds the audio should remain unmuted. Keep in mind also the green busy LED flashes only if that channel in the M...

Economics will also play into such a move in the aviation system. To make a change like this, every civil aircraft and ground station in the world would have to make the change at the same time of the same day. With the airlines claiming such financial difficulties as they are, they'd never be force...

I have a Motorola branded ball mount here. I also have a Hustler SSM-1 (ball and spring sold together) that aside from not being stamped "Motorola" on the insulator, appears absolutely identical to the M mount. I'd be willing to bet they came from the same factory. And the Hustler has held...

Correct and correct. Each company has called it a different trademarked name, but it all boils down to the same thing. GE called it CG - Channel Guard. RCA called it QC - Quiet Channel. Most everyone calls it PL just like they call all hand helds "HTs." Both PL and HT are Motorola trademar...

So if I use the radios on a frequency that is 1mhz different, it will fry the radios? As N5TBU said, the duplexer is much narrower than that. In a non duplexer situation, just a base or mobile radio and antenna, 1 MHz would not matter. But with a duplexer, the 150 KHz difference you describe is too...

wa2zdy

Ok now I have a duplexer on 462.700/467.700. If I transmit on 462.550 and RX on 467.550, will there be alot of signal/power losss? Or will the difference not be noticeable? Get it tuned for your frequency pair or you're gonna have a very poor repeater, then no receiver when the front end gets fried...

wa2zdy

Not to sound snippy, but if you have to ask here how to do it, you have niether the equipment nor experience to do it correctly.

Your call for help is the best action you could have taken.

wa2zdy

The manual says the T73 draws 28A key down.

wa2zdy

more power isn't always going to be your key to better coverage either, the more height you can get out of you antennae the better. i think i'd take 5 watts 200 feet in the air over 100 watts on a vehicle roof. Ywp, invest in antenna quality then gain, and height. Those factors help your receive to...

I should have seen that in his signature. I stand corrected.

The technical issues are unchanged however.

Do it behind the front panel, it's easy, and never have to worry about it again.

wa2zdy

You cannot run a repeater on a single frequency, no. Unless it's a time delay playback thing and I think those are no legal for Part 90 use. Unless your two antennas are hundreds of feet apart horizontally or 40 feet or so one above the other, you will need a duplexer. Without a duplexer or enough p...

Andy's the man for the job.

Cute little radio indeed, but as already said above, best off in a display case.

wa2zdy

I just added to that forum on RR and my comments may help you.

wa2zdy

The audio from the narrowband transmitter will sound low to the Saber, and the transmit audio from the Saber will be distorted in the narrow receiver. It may in fact cut out while overdeviating.

It might work but it won't be pleasant overall.

wa2zdy

Also, the radios would be used while on the ship only. We would have no use for them while in port anyway, and I am quite sure that using them in another country would not be permissable... As I said, aboard ship your operation would be subject to the laws of the ship's nation of registry. I doubt ...

wa2zdy

A guy on qrz.com asked a similar question. He wrote to the cruise line who told him using ham radios on the ship was not permitted. Strike one. If you're speaking strictly from a legal standpoint, your radios need to be licensed in the country of ship's registry for use on board. A ship at sea is so...

wa2zdy

Yeah Paul, nothing rare about them. I've had dozens of all three varieties - HT600, P200, MT1000. I've wondered who used them too but eh, they've been good for echolink and such, so I don't wonder too much. Some of them are odd though. The programmable fronts require a double push of the # and * to ...

And that makes that radio sort of not too useful here in the US. A public safety agency above Line A could use it if it was conventional, but . . . for ham use it's pretty well useless as FM activity is mainly above 440.[/b]

wa2zdy

It sounds to me like you've rigged up some sort of system to key the transmitter based on received audio. Ordinarily the transmitter is keyed by a carrier operated relay. This is activated by either a carrier or the correct PL tone, not by audio from the speaker. Either I'm not understanding correct...

Properly fuse both orange and green lines, connect them to the main red power line and just remember to turn the radio off when you park the car at night. Eliminate the whole issue.

wa2zdy

The power consists of a six gauge bat pos and bat ground, both of which are fused at the battery. This then goes to the individual radio fuses. My voltage regulator post refers to a bench power supply. You should not have this issue in the car. Get rid of the negative lead to the battery. I'll bet ...

wa2zdy

If this is on the bench, be sure RF isn't shutting the regulator down in the power supply. Common problem often overlooked.

wa2zdy

As Will said, HT600 and P200 RSS are interchangeable except for the low band P200 version. There is no low band HT600.

wa2zdy

if everyone else is doing it and it does good Most land mobile systems are designed as one with specific goals in the design. A local agency or business knows where their mobiles and handhelds will be. They can design the repeater or base to give xx% coverage into specific areas with antennas of wh...

The MT1000s could take this.

Yeah well, there's a reason the Genesis radios are considered the second best HT ever made, after the first place MT500.

wa2zdy

You should put them where you want them. The rule of thumb to avoid interaction between the antennas is that they be spaced at least a quarter wave from each other. In the case of a multiband antenna, that means a quarter wave at the lowest frequency. And if two antennas on different bands, they nee...

wa2zdy

Anything can be repaired. The question is, how much money do you have? It doesn't transmit or receive better I'd bet because the antenna is no longer properly connected to the board. A nearby radio will hear it though, until you fry the final doing that. Yep, if you have enough $$$ you can get it fi...

That's a 45 watt radio. If you're reading 80w out, something is wrong with the PA (it's going to nuke itself in short order) or your wattmeter/load is defective. If you are not using a 50 ohm dummy load, you cannot depend on the wattmeter readings. And if the load impedance is way off, that will cau...

I meant that being only a tenth of a cycle off, it should be close enough to decode the tone.

wa2zdy

My MT2000 is so programmed and yes, the MURS freqs are at 2w and the 151.xx freqs are narrowband. The way I interpret Part 95 this is legal. I sure hope I'm correct.

wa2zdy

I never tried it but a tenth of a cycle? I'd think that should be close enough. I guess you'll find out. Maybe I'll try it too being here where the weather gets bad from time to time!

wa2zdy

If there had been a fuse in there as Jack mentioned, it would have blown before any damage had resulted. The protection diode, like any diode, conducts only when the anode is positive. It's installed so the anode is on the negative power lead. So it only conducts if the supply is connected backwards...

Analog is OLD and outdated. Digital and encryption is the new thing. I use ham radio almost every day... how much of that do you think isn't encrypted? Both the FCC and IC just don't care about ham, GMRS, CB or FRS. And N1PFC said: Encryption on the ham bands is ILLEGAL. PERIOD. read 47CFR97.113 so...
