I am going thru a variety of projects presently and am now at the omni V ...it seems on most bands above 80 m if I increase power to past 3/4 point the display blanks out and it gets stuck in tx mode
Sounds like RF feedback. This can be a tough one to figure out. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com On 2/24/2014 5:29 PM, Scott Shepard wrote: I am going thru a variety
What's your power supply? Sounds like RF feedback. This can be a tough one to figure out. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com On 2/24/2014 5:29 PM, Scott Shepard wrote:

I have a run of LMR 400 out to the hex beam over 140 feet away. PWRs supply is 32 amp switching but it does same on TT supply as well...cw key down or ssb voice peaks...same effect. I will play aroun
Er, does WHAT happen to you?? _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
Might be. Suggestion #1 gets both to that and the PS voltage issue. 1. Try it on a known good dummy load with a known good jumper between the radio and the load. 2. Make sure the DC power connections
Jim mentions the RCA connectors on the rear. Please understand the Audio IN on the rear is the same exact input only isolated by a 22K resistor from the mike input on the front. Anything that is conn
Make sure the ground screw on the rear is very tight. The DC negative from the 4 pin power connector on the rear gets its connection to chassis and system ground under this screw on the inside. I dou
The earth is NOT a sump into which RFI and noise can be poured. A connection to earth is almost never part of a solution to these problems, nor does it make an antenna work better. What DOES matter,
There are so many possible causes for this problem. In avionics installations, we try to keep all transmission lines from various radios away from each other as much as possible. Maybe a coax line in
That ground screw on the rear is also used on the inside to connect the DC negative to chassis. It then protrudes to the outside for the radio ground terminal. 73 Bob, K4TAX The earth is NOT a sump i

Problem found-: m it was my ameritron 4 position band switch...the Lind that uses the coax to send the signal down line to change antennas....why am I not surprised?? Easy fix...sort of. Thanks to al
