Bug Out Transmitter
Quansheng VHF Radio
Here's a tiny, compact VHF transceiver that should fit any bug out bag. 137 to 174 Mhz Tx/Rx uninterrupted. Programs from keypad up to 99 channels. Repeater capable CTCSS. 1 watt / 5 watt output. Its a great HAM radio, a business band radio, operates on MURS channels and fills in as a police scanner if you don't load up too many channels. You don't need to be a HAM operator to own one, just stay off the 2 meter band. I use mine with my base or mobile MURS radios. Under $100 on ebay, shipped from manufactor. http://www.usa-battery.com/images/Quanshengradio.jpg |

What kind of distance can thoses opperate at? In Cities or in the Country what would the range be?

Re: Bug Out Transmitter
VHF is the best band for rural comms. Pending on location and terrain. Pending on what your transmitting to.
HT to HT is most limited, HT to Mobile is better, HT to a good base station is best because of antenna and power. In a SHTF situation I'd climb the tallest location and transmit from there. My mobile to base has about 10 mile range, my base to HT is good for about 2 miles but its all about location. At my uncles place (bluff over river valley) I can get almost 7 miles to my mobile on this little radio. |
Re: Bug Out Transmitter
yea these are pretty good radios for the price. I have 2 of them, 70cm and a 2m band one. The 70cm VHF has slightly better range. The build is pretty solid. Easy to program up. Work well on repeaters. Sound good. Haven't found anything wrong with them. I have the tg-45AT and the tg-25AT(?)
I put a dual band antenna on my vehicle. I then just plug one of these in while I am driving around. Works well. |

CAVEAT: These radios are sometimes sold in flea markets, etc., backyard vendors and the like. Their importation is a grey area, the FCC says they are not approved for use in the USA, however hams can import radios for their use (NOT FOR SALE) and the ham is solely responsable for his or her emissions and how they conform to Part 97. Use outside of the HAM BANDS 144-148 &430-450 is basically in violation of Parts 95, 97, 80, & 90 since the radio is not type approved. |

Got a couple a while back, they are knock-off ICOMS, but the FM had a little distortion, not bad for $60 radio. The reason I try to install a little radio discipline here is that if you have any problems with "illegal" radios like transmitting on the Police Band or blocking up an industrial repeater, then the outcome "IF CAUGHT" will not be good. Here in S. Louisiana, some noobs got some Yeasu Radios, done the MARS MOD and widebanded them then went looking for a quiet frequency to chat on. They installed them on every Shrimp Boat and in the houses to talk and with the proliferation of Oil Companies, pipeline and refineries, somebody got on somebody elses Business and Industrial Frequency and blocked something up. The Oil industry (other commercial users as well) use radio for telemetry and control as well as voice in the VHF spectrum and therein lies the rub, the FM voice would override the telemetry and control system causing a packet crash setting the Watchdog loose causing a plant shutdown or device shutdown. SHUTDOWNS are VERY EXPENSIVE TO SAY THE LEAST, HARD TO GET IN THE WAY OF A MILLION DOLLAR OPERATION so something had to give, the hams in the area had already run the unlicensed noobs off the repeaters and ham freqs but when BIGGGGG $$$$ OIL is pissed, they call out the heavy machinery. They (some communication companies) put up some doppler reception stations in the area and started monitoring the bands for the offenders by using; http://www.dopsys.com/ser5900.htm Which once the ring leaders were identified, the FCC got involved and the offenders got a visit, either from an FCC, USCG or Marshalls Office about the radio. A few wannabe tough guys said what they would do to the FCC man if they caught him (Fishermen makeout like wise guys) but in the end, radios were removed from Shrimp and Fishing Boats, base stations were dismantled and some even got Ham Licenses to use the stuff on 2 meters to call home. One wiseguy in the neighborhood who would make fun of my "HAMMIE STUFF" was calling the house from his lawyer's office to see what can be done about this "FCC Letter" because the Lawyer knew I was a HAM RADIO OP and Louisiana Paralegal, the basic line was to cease and desist immediately and cooperate with all future inquiries, I was stuck to explain that once the FCC had these facts, the location and monitoring tapes, it was deer in the headlight time. The lawyer advised his client to comply, and the lawyer had his client deliver the radios to my house with me giving him a reciept for them (Donated to Civil Defense) as a Licensed Ham radio Op who could take possession and use without further questions. The sheriff's office ended up with some primo stuff and we were ready when KATRINA hit town!!!! 2 Meter radios everywhere!!! Bottom Line, $11,000 a day fine, max, $88,000 for illegal use however prosecution of Comm Act of 1934 is considered a Felony if you want to know. And yes a felony says bye-bye to your preps. |

Re: Bug Out Transmitter
Ok. so i'm new to the radio stuff. got myself the tech ticket and just bought a yaesu vx7r. (not recieved it yet)
this thread brings up an interesting topic... what are the bands that HAMs are not allowed to transmit on (official use only), but might be interesting to monitor? do some of them require specific hardware, like the military radio stuff? links to good info? |
Re: Bug Out Transmitter
Hams can use any frequency in emergency's
If there is danger to life and limb or property. In those times hams can go on the public safety frequency's and call for help. The public service frequency's are to many to list here, but are good to monitor ,The freq's used , vary to the state and region you are in. If a member of MARS, Hams can use Military MARS frequency's (Iptuous You are going to like that vx-7r) In normal times: Hams can use these frequency's and bands for normal use.

Re: Bug Out Transmitter
QWAK,Back in 71 at Ft. Monmouth in RADAR repair training on of the guys left the DUMMY LOAD off of the IFF transmitter BIG OOPS:yes::36_1_30::36_1_25: New York city is close to Ft. Monmouth and there are BIG airports and smaller ones all over the place!:yes:
For about 15 min. IFF TRANSPONDERS and and controll towers were going NUTS!:yes::4_1_72::evil::111: It was NOT me:wink::452: but I did get blamed for droping a WASHER down a $2000.00 piece of SILVER lined WAVE guide and FRYING IT!:yes: I picked up a military PACK radiofrom the 50s that was intended for air drops behind enemy lines -- IT has a DESTRUCT plug in the center (explocives removed) that would render it useless when trigered!:yes: Brand NEW never issued with antenna mast and guy wires -- even a DRY wet sell battery -- just ADD WATER! It has VACUUME penut tubes -- NO TRANSISTORS or CHIPS,air capasitor tuning! I have never fired it up -- bought it back in the late 70s for $40.00 if I remember right at a surpluss place. It has a heavely padded case with a huge SNAP atached for snaping on to a parachot or hanging it on a pack anamal orwhat ever.:s1: Ther was no microphone :( so would have to get a head set and I never did. BTW: In Nam the VC took cheep small portable B+W TVs and cliped the tuning coils and listened in on FM feald comunications IF it was not on a SCRAMBLER -- the VC were way smarter than our government told the public!:yes: the DUCK |

I would place a bet ,,it will... If you know any hams in your area,, may be fun to see if it does... The only thing that would worry me would be the electrolytic caps , being dry.. But Mili spec..maybe not. :ok: |
Re: Bug Out Transmitter
QWAK,Golddust,Don't know any HAMS and it has been SOooooooooooo long since I was in electronics the only part that may be of use to ME, would likely be the FM antena and mast and guy wires for use on an FM han unit to extend range.
IT is a cool radio for a collector!:yes: Hopfully once I get this new puter set up I will be able to post some pictures agen! :s1: the DUCK |

There are tons of frequencies that the vx7r could pick up, but if they don't want you listening you won't hear it. A lot of air force stuff happens near 300~400 MHz If I remember correctly. The next time you're at your favorite periodicals stand look for Monitoring Times: http://www.monitoringtimes.com/ They usually post airbase freqs and stuff like that. |
Re: Bug Out Transmitter
Oh and here are some modifications you can do to your VX7R that will do neat things!
http://www.ham.dmz.ro/yaesu/vx-7r.php http://www.kb2ljj.com/data/yaesu/vx-7r.htm Be ginger on the inside! Hell who am I kidding you're an EE! I'll now wait for every other HAM in the forum to call me a doo doo head for posting these links. :) |
Re: Bug Out Transmitter
It's not cheap, but if you're looking for a "real" HT, I highly recommend the Icom IC-92AD with D-Star. D-Star is cool because it allows HT-to-HT digital communications. You can also use a digital repeater that will forward your conversation over the Internet and then re-transmit it in another country.
