I just got my first mobile, a used HTX-212 (45W on high power).. When
I have the car engine off the transmit bars only light up about half way. When I drive they go up farther but I still have trouble hitting the repeater while my HT hits it with no problem. Are these power fluctuations normal? Thanks, Dan KE5BCC |

Thanks, Dan KE5BCC that is definetally not normal. do you have a SWR meter ? or any kind of meter you can attach to the radio to see what is coming out of it ? how is the 242 on receiveing in comparison to the ht ? -- Registered Linux User #346565 http://www.tblx.net WA5K |

Hi, Since you are new to the hobby (congratulations) is your antenna
correctly mounted (grounded OK)? How is the coax cable run, could you have "pinched" it or cut it pulling it through metal parts of your car, maybe causing a short in the cable? It sounds like it is an antenna issue. It sounds like the radio is folding back it's power for protection. If you don't have an swr meter, get one or borrow one. Also, see if you can borrow a magnetic mount antenna for a quick test. If that works OK then it is an antenna / coax problem. One more thing you can try if your antenna seems ok. Add a small coax jumper (a foot long or so) between the radio and the antenna coax. Once in a blue the added length of coax can cure some SWR problems. 73 and good luck!!

Thanks, Dan KE5BCC What is the gauge of wire (for power) you have feeding the transciever??? and how long??? Where is your power lead hooked in??? Is it hooked into the battery or do you have it running through the fuse panel???? -- One lawyer can steal more than a hundred men with guns. |

I have an SWR meter but it is for 10/11 meter only. I think I
discovered "half" of the problem.. The power cable was passing directly over the antenna coax. I separated them with about 6 inches of space and the radio now hits many more repeaters than my HT, however the power meter still only goes up half way. The receive is very good. I am able to pull in all of the Wx channels on 162.xx.. Can't even do that with my scanner and an attic antenna. The 1/2 of the bars when transmitting still bugs me though..

12 feet of RG58, plugged into the cigar lighter using one of those
radio shack adapters. I tried hooking it directly up to the battery and had the same problem. Also hooked it up to a 10Amp power supply.
