Dave: Did you try rewiring the mic element so that it is powered all the time? Maybe the mic power is going through the PTT switch and the turn-on transient is putting out an audio pulse. 73, Bob WB2
Dave: Well, the only other thing that can suggest is an RC circuit on the power input to the mic to slow down the rise time. 73, Bob WB2VUF Yes I did wire the voltage hot all the time as a test. The
Good, job, Dave! It's always a joy to fix or improve something. 73, Bob WB2VUF On 12/18/2010 8:35 PM, K8JDC wrote: For what it is worth, I got rid of the big spike by making two changes. First, there
Alan: I have a 1254 and really like it. It is sensitive and stable. The steel case makes it rugged and professional looking. It has a balanced JFET mixer in the front end and an AGC-driven automatic
Alan: Merry Christmas! Thank you for the links. I was aware of the mods on Marshall Emm's (mtechnologies) web site, but the replacement processor mod is really exciting. It would bring the receiver c
Alan: No, I don't have any processor problems. I was referring to the mod kit available here: http://www.cholakian.com/TT1254upgrade.html, although I don't find the coarse tuning steps of the 1254 th
Thanks, Dr. Gerry, That's interesting info. My Scout is spec'd at 600 mA on receive. I typically run it at 30W and have had excellent results using a low (NVIS) portable reel-out dipole made of AN/CR
I forgot to mention that there are video demos of some of the Ten-Tec kit receivers on youtube, including a demo of the 1254 by Scott Robbins on Ten-Tec TV. Bob WB2VUF _http://www.mtechnologies.com/t

We called it "short skip", during my misspent youth. From my Novice days in 1966 to the present, I don't think I've ever had an antenna higher than about 25 feet anyway. I work mostly 80 m traffic ne
I have the original Paragon and find it to be a versatile rig. I had problems with the PLL boards that I solved by reflowing the solder. This is not a problem with later Paragons. Ten Tec redesigned
I use the Ten Tec green grease, which is described as "open gear grease". The PTO rebuild kit comes with plenty of grease. I tried a lighter synthetic grease, but the PTO spring tension working again
I have seen ads in the radio magazines for a DDS VFO. It's not advertised as a replacement for any current VFO, but it might do the job. It would be an interesting science project. 73, Bob WB2VUF On
No antenna = no Ten Tec. The problem goes much deeper than ham antennas. How about the veteran medal of honor recipient who was persecuted by the HOA because he wanted to fly the flag to honor his fa
Could one set up a fake satellite dish, using the coaxial cable as a random wire antenna and the dish as a capacitance hat? One would still need a counterpoise, of course. 73, Bob WB2VUF The PA HOA i

Yes, you really don't need to replace parts unless they are badly worn. Usually a cleaning and re-lube will do the trick. Be careful with WD-40, though. Someone on this reflector said that it can cor

I thought that all MARS gear now has to meet a 20 ppm, I think, NTIA frequency stability spec, which requires the purchase of commercial/military gear such as Harris or Motorola. Bob WB2VUF Very good
