Help: Two-way Radio

[OTEP]

Hi guys, found an old Kenwood TR-9130, 2m All Mode Transceiver. To give you an idea kung gaano ka-antique ito, here's a photo:


At work, we use the somewhat newer Motorola GM300:


I was looking at the NTC registration at the office and it says that the registered frequency is 158.650mhz.

I don't know much about radio communications. I'd just like to ask if there's any way I can use the Kenwood to listen in (no real need for transmission capability) to the GM 300? The frequency display of the Kenwood ranges from 3.90-8.99 (no idea on the unit of measure).

Thanks. Sorry, I'm such a caveman when it comes to these things.

google indicates yes, there is a good chance it will work ... set the TR-9130 to FM mode because GM-300 is FM only, any frequency (3.90 means 143.90 MHz) then let the GM-300 scan for signals ... good luck!

Thanks. Malabo atang mahabol ko yung frequency na gamit sa office nito. Kasi 158.650mhz na yun. If I go by your explanation , hanggang 148.99 lang ang kaya ng TR-9130.

Hindi ko pwede kalikutin yung radio sa office baka hindi maka-contact yung mga ambulance at field personell.

ay ... naka-fix pala sa 158.65 yung GM-300 for office use ... malabo nga

Sayang, mas nakaka-aliw pa naman sa telenobela ang mga usapan dun. hehehe.

Otep- yung range ng kenwood is set up in the amateur band that is in the 14 mgh, pwede mo yan ipabatak sa mga radio technician para umabot ka sa 15 megs or sa 13 meg.

[OTEP]

Pwede pala yun? Saan ba may mga ok na radio techs/shop sa Metro Manila? Any idea po sa cost ng work? Thanks.

Wala na kasi yung mga gumagawa samin dati. Wala kasing landline sa lugar namin. 1993 na nagkaron kaya gamit na gamit ang mga 2-way. Nung dumating na landline, tinambak na lang.

Sa Raon madami, puntahan mo nalang yung mga nagbebenta ng mga 2 way radio, usually may mga technician yun. Minimal lang naman ang fee ng mga yun. Mataas na ang five hundred.
Pero you must asked them also kung anong antenna ang nababagay sa 15 megz kaya baka pang 14 megz lang yung stock antennae nya.

Nasa bubuong ng bahay yung antenna. Ang taas pa naman ng bubong. hehehe. Yung gumawa pa ng bahay ang nagkabit nung antenna dati (a long, long time ago).

Mahirap pa ba kumuha ng NTC license ngayon? Ano ba kinukuha ng lisensya, yung radyo or yung operator?

[archangel_1911]

nasa bubong? well maybe pwede naman yun kaya lang para mas maganda reception nya kung yung designed sa higher frequencies yung antennae.
Yes pwede na siguro sa yo ang RLM yata cant remember pero it means restricted land mobile. anyway nasa commercial frequency ka naman. Pero kung matagal na yang antennae mo sa bubong at d naman nasisita ok lang yan.:D Pagnasita atsaka ka nalang magpalicense.

That depends on the kind of radio service, but it's usually both. Since the TR-9130 is an amateur radio, you can only use it on the amateur radio band. The applicant has to pass an exam to get a license, and the radio has to be registered to be used. You don't have to be a rocket scientist to pass the exam .

Doc, that particular model was designed with a narrow bandwidth receiver, optimized for 144-148 MHz. You can shift the 10 MHz upper/lower limits, from 140-150 MHz to say, 150-160 MHz, but receiver sensitivity suffers a lot ... unless you modify the tuned circuits, too. Which is like saying - better get another radio.

Dismantled na yung set up, nahalukay ko lang. Paso na din license. Yung antenna sa bubong, ang kasama ay yung antenna ng FEN (does anyone remember that TV station? hehehe). No one just bothered to take it down.

Yung mga 'scanners' ba kailangan din ng license even it is only for receiving and not transmitting?

[StraightSix]

Yup, I remember that
Nakukuha ko nuon sa Baguio ang signal niyan sa Clark. I remember using a DIY'ed quagi antenna for that (combination quad and yagi). Ang tagal na niyang antenna mo ah, hehe. Kalaban mo kasi sa antenna yung corrosion sa contacts.

I've met a number of pinoy scanner enthusiasts/SWL's (shortwave listeners) in my life, and I can't remember anyone mentioning a need for a license. Countries usually don't require one when you can only receive, although some may impose conditions like you can't listen on police and cellular phone frequencies, or use it while mobile. Most scanners have these radio bands already blocked out, but some models can receive continously between the limits.

I used to have a Realistic handheld scanner which I "unblocked". For a while it was entertaining to listen to cellular conversations. The networks were still analog then, like Mobiline. But getting into the conversation is much better for me .

Otep,

I've used a 9130 before...back in the 80s. It's a good radio, all mode...meaning it's capable of different type of modulation implementation (e.g. SSB, FM, AM).

The model was highly regarded for it's ability to distinguish, between a true signal and a harmonic or undesirable signal (splatters). The splatters was a concern back in the 80s, when there were so many illegals bootlegging the channels.

As mentioned by many, it was designed for electronics hobbyist on amateur radio. To my knowledge, it will only work between 144 to 148 MHz.

Here is the Philippines, the legal frequencies for 2M amateur radio is 144 to 146MHz. You will need to take a qualifying exams at NTC for licensing.

As for expanding the frequency for the 9130 to work on 158MHz - probability is very slim. Also, it is unlikely that NTC will allow you to register a radio used for amateur radio for commercial purposes/professional use.

Nevertheless, the 9130 is a classic and will remain so.

If you're interested to join the local amateur radio community, I suggest you check out www.para.org.ph

BTW, the "4.300.0" on the picture means 144.3000 MHz.

Nice info Thanks!
