Im studying right now to take my test on the 16th. The radio (Yaesu 1802m) is going in within the next week or two.

I feel this is a absolute must for any overland/expedition rig that may travel out into remote areas. This last mod, will finish up my 1 year build up and we are really excited to start using the airwaves.

Who here is running a 2meter radio?
 
Been slacking on this since a year ago. I almost took the test back in June...yadayadayada

To F'n answer your question, Im taking the exam on the 14th and I will be have a 2M before the summer is out (paying for the sliders comes first :D).

I guess Im committed to take the exam now. :doh:
 
I got licensed about a month ago. Purchased a Yaseu VX7 HT and looking to get a mobile soon.

Good luck on the test...If I can pass anyone can.

cheers,

yup, here in N SoCal... :)

been playing with Laguna Niguel, PV and other repeaters...

we oughta do a net sometime...!
 
2 meter, yaesu, listened in moab, still have to take my exam, I was amazed at how far line of site you can broadcast, makes a cb look like a toy....
 
I just did about 130 miles with only 5W out of 50 (with good antenna and on a mountain side...)
 
My race radio is narrow band that obviously doesn't get as far as the wide band but I am curious does anyone know if a wide band 2 meter radio and a narrow band 2 meter can communicate within the limitations of the narrow band radio?

Hey Mo, just learning 2M from a blank slate but found a possible answer to your question.

http://www.asti-usa.com/support/appnotes/58.html - go down the page where I cut/paste from. I hope it helps.

Narrow-Band versus Wide-Band Radios

One likely scenario that you may encounter is finding two radios in the same frequency band with each radio having a different bandwidth. This is illustrated graphically in Figure 5.

View attachment 156653

Figure 5
We can see that the two radios have different bandwidths. Radio 1 is a wide-band radio, while radio 2 is a narrow-band radio. This can result in a potentially confusing communications scenario, because the wide-band radio may receive from the narrow-band radio, but the narrow-band radio may not receive the wide-band transmission. The wide-band radio acts as a jammer to the narrow-band radio when it transmits.


Simulation Hint
If there is a mix of wide- and narrow-band radios in use, and you want to make the instructor’s job easier try the following: Substitute separate transmitter and receiver objects for the instructor radios. Make the transmitter narrow-band and the receiver wide-band. Your instructor will always be able to transmit to wide- or narrow-band radios. Additionally, your instructor will always be able to receive from narrow- or wide-band transmitters.

Is your race radio a MURS radio?

What is narrow band vs. wide band?

The Federal Communications Commission (FCC), in order to make more room for more radio users, has begun to require that user of the VHF band to use less bandwidth in their communications. Many users have already begun to migrate toward narrow band. MURS is unusual as it allows both narrow band on all five frequencies and wide band on two of these five. This is to accomodate users on the two frequencies who were grandfathered into the service. It is recommend that you use narrowband on on all the MURS frequencies.



Can this radio do both narrow band and wide band?

The Kenwood TK2100's programming software can do either narrow band or wide band for all memories but cannot be programmed on a per frequency basis. For instance, all MURS frequencies are programmed narrow band by default. If you want use this radio in the 2 meter amateur radio band, then all frequencies would need to be programmed wide band to be compatible with other users. To stay legal, you would need to use only the upper two MURS frequencies (154.570 and 154.600) since you are allowed to use wide band on these frequencies.

And, i don't know if you need to get your tech license to be able to key up. You might.
 
Thank you both Alan and Dave. I will have to look into it a little more with a buddy of mine. I have been using my Pop's call sign forever now. I studied with him but never got my own number. That was also 15 or so years ago. Now that more people are getting 2M I would like to get legal and join in on the fun.
 
I passed the Technician class exam today - there were a couple of Rover guys that took it too (hehehe I definitely made more correct choices in comparison - just joking).

Now I can casually read up on 2M (HAM) without worrying about passing the test - no radio/antenna yet but $$$oon.

Dave - good luck on your exam. :beer:

well, now that the world knows about this, behold the black helos and triangulating vans... :D

:lol::lol:, I had better go close the blinds and shut her down. ;p

I misspoke a little. I have not even powered up my wide band 2m let alone used my dads call sign in about 10 years. I do need to get my own sometime though. Just gotta find time. :rolleyes: :D
 
About half way thru Gordon West's book - got lots of reading done flying to and from Chicago this week. No idea when I'll take the test tho.
 
Ok, I found out a little more on the conversing between radios issue. My radio is capable of reaching all the bands I just need to make sure I have my ticket before I chat up on the 144mhz side. If I get that taken care of and my antenna bleed over issue taken care of I will be set to chat with all of my SoCal 80's bretheren on the HAM side and the CB side without blowing everything out of the water. :grinpimp:
 
My radio covers 144mhz to the mid 150 mhz's. It has been, Ahem..., "modified" to cover a much larger range of frequencies. :D The only drawback is that the antenna is tuned to the optimal frequency I use the most so I will not get as far the further I get from it's tuned frequency. I started with a break before make antenna switch to run my cb at 27mhz or my race radio at 151hmz with the same antenna base in the roof but the 2 meter blew the cb out of the water even when it was turned off. I then switched to a duplexer to better isolate the two systems but that has now failed so I am just going to add a second antenna base and keep the two completely seperate. Alvaro has used that system with success so I will likely follow his lead. I will either get another 2 meter and tune it to the 144 mhz range or live with less than optimal output with the one I have that is now tuned to 151mhz.

seems likely that an antenna tuned to 151 would do fine at 144. Difference is small, consider the type of compromise one does routinely with dual band antennae for example?


(ahem: even more black helos now... you're just lucky there are all these fires around, otherwise you'd already been nabbed... :D)
