If a radio receives but won't send, is it shot or should I be checking out antanna problems ?.. everything seems fine from the outside.
 
nedarb2 might be right. I have an older Motorola radio that has a bad mic. The cost of replacing it with a new one is almost the cost of a new radio. Most likely the wires in the cord.

Question: When you key the mic, does it indicate that it is transmitting, and does it send out an dead carrier?

If yes, probably the mic.

If no, could still be the mic, or it could be the finals in the transmitter. If it is the transmitter, sell it on ebay for parts and buy a new radio. Also make sure your antenna is in good condition, as that could be the cause of your transmitter burning out.

Good luck,

sometimes water gets into the mic and just needs to be taken apart and dried.

Oh.. it that what that is ! The transmit light comes on, but I think you're saying that doesn't necessarily mean it's working.
Now, is the transmitter the radio itself ? Or maybe I don't have one !! Just got this boat.
 
the transmitter will be in and out of the antenna... the button on your mic is probably working but the part that hears and inputs sound might be shot... new vhf's are like 100$ if there is any doubt.. try looking on ebay for a new mic- if u have any buds with boats try stealing their mic - if its the same vhf brand - and trying that out
 
It is relatively easy to test a VHF. If you are hearing a signal, say from cost guard, the chances are your antenna is good. If you press the transmit and there is carrier but no voice, it is the microphone or the input audio stage. If the radio looks like it is transmitting but there is no output, the problem is more serious. But, the problem may be a bad voltage connection or a drop in voltage to theradio. Transmitting takes more current than receive and additional problems may show up.

Best way is to bench check the radio on a good power supply and into a dummy load. I could do that for anyone in the Parksville/Qualicum area.

If the radio is not working, it is not normally worth the cost of repair. I posted this to your want ad;

I just received a flyer from Radioworld in Toronto, www.radiworld.ca They have a sale on a couple of marine VHF radios;

Eagle EVR-150 25 watt Marine Fixed mount - $90.00
Eagle EHR-10 5 watt marine handheld - $70.00

Remember that you need a licence to have one of these in the boat. Should you get checked, it could be a $250.00 fine if you don't have a licence.

Good luck.

Guy at Harbour Chandler seems positive it's the antenna, so I bought one and will try that first.. That is a good price for new ones so you may be hearing from me soon.. thanks for all the feedback.
 
Get your self a good quality antenna. We had cheap antenna and the reception was terrible, there was a thread on this forum a few years ago about antennas, I took the advise and went out and bought a high quality antenna, oh MY! what a world of difference ! I will try to find that thread here and post it..
 
I did a search and found it.. Shakespeare VHF 5225
http://www.sportfishingbc.com/forum/topic.asp?TOPIC_ID=5079&SearchTerms=antenna

I took the advise from this thread and bought this antenna, Shakespeare VHF 5225 to replace our cheap one we had on our boat t that had pour reception and transmission.. well.. the difference is unbeleivable!! Our boat parked in my back yard we were picking up radio conversations from the Fraser river !

Highly reccomend getting a good antenna !

Here is the actual post I am refering to... I took his advise and it was bang on !

Make sure and get the more expensive antenna. This is night and day on a VHF radio. Buy the 40 or 50 dollar one and don't expect to broadcast far. I would get the Shakespeare VHF 5225. You will not be sorry. Its about $135.00. I have another friend that showed me this. I bought the cheap one and then bought a good one. Between both of us, we CAN talk where line of sight does not exist.

We have talked to each other from opposite sides of Whidbey Island where the land is really high and I was in the Strait of Juan deFuca in the mouth, about 2-3 miles inland, while he was 20 miles south down the coast. There were huge mountains in the way and we talked easily. I thought he was pulling my leg until I asked the other guys in the other boats if he was really there. They verified it. In fact we have guys hail us to relay messages to the guys with the poor antennas as they cannot broadcast out to be reached.

The most expensive radio does no good with a cheap antenna. Oh and get the 8' antenna. The better antenna is heavier too.

Thanks Rock.. that is great advice.. unfortunately I already bought the $50 one... But at least that should determine if the old antenna is the actual problem. Maybe I'll have to post the chaep one on the Buy Sell... shhhh
 
Sell the 50 buck antenna and buy a Digital brand antenna or the one suggested above (which may be the same technology as the Digital) My Digital is amazing. I think they use magnets instead of coil or something like that ?? Yes it was about 200 bucks but worth it - it transmitts from Ferrier Pt to Tahsis village without too much difficulty. The higher off the water the better and my antenna base is a mear 3' off the water on a 17' boat and still does very well!

A common misconception is that if you recieve a signal well that it means you have a really good antenna. While it helps, thats not really the main reason you get a good signal. You can recieve with a rubber ducky or even a coat hanger if the transnmitter has a good antenna. Its the transmitting radio/antenna/mic that is getting a radio 'out' well that is the main reason for recieving a good signal . If both stations have good radio/ mic and antenna than that is obviously the best senario.


Cohochinook, check out this thread on VHF radios in the Sport fishing 'Open' forum. Class D vs DSC VHF radios are discussed

NOTE to add to above :
The person transmitting (and his equipment he is transmitting with) is what I meant when I said the "transmitter" . As opposed to "reciever" being the boat receiving the signal.
