I'm sure I'm not the only one who has had one of these tiny things magically disappear during a rebuild. Other than ordering a handful of replacements from Ten Tec, has anyone had success with altern
The type of RX antenna and QTH noise floor certainly play no small part as well. My Omni V is no slouch in the RX capability dept., but I could never hear the beacon when the power dropped below 5 mW
Yup, the "plain" Omni A is the one with the squelch control. Some day, I'll make better use of that pot on my Omni A - probably a variable notch filter. Al, K2ZN John N1JM This is getting as bad as "
Just in time for next weekend's VHF contest: Model 1208 6m to 20m xvtr, 8 watts out. Build by me and tested/aligned in my lab at work. Includes manual, $75 + shipping. Model 1210 2m to 10m, 8 watts o
Has anyone experienced a lack of messages from the list for several days, then have the dam break? I had some 280+ Ten Tec messages held over since last Friday or so that started blasting in this mor
Perhaps the broadcast email was the problem; I had restarted my computer the other day, but hadn't checked for new mail until I used webmail this morning. I think I've had a similar problem with a di
An even better implementation of the SCAF filter would be to get it within the audio AGC loop. I set up my Omni A that way with a Datong FL3 - outstanding! Al, K2ZN
Yup, I've had dismal results with DSP boxes as well. They provide hundreds of microseconds of delay, if not milliseconds; ADC bit noise as well. The FL3 delay is in the tens of microseconds; comparis
Joe I've got such a switching arrangement for my ancient Microwave Modules 50, 144, 222, and 432 transverters and haven't noticed any impact on performance. I'm using a Corsair as the IF - the TX oup
HF prop still seems to be fairly decent here in Singapore, at least compared to the lousy conditions I usually encounter over here. With such a high noise floor, it's hard to tell. Being near the equ
Depending upon how often the network has to tune an impedance with a very low R component, it may be worth the effort and expense to replace the ceramic disk caps with something more robust, like an
Rich With regard to the band switch, make sure that the linkage between the two switches is intact. There should be two small brass rods held in place with little plastic buttons. If the rods are ben
Hi I'm putting together some winter projects, and would like to resurrect one of these fine old rigs. What have you got? Please respond off list. 73 - Al, K2ZN
Last year, I built up such a beast with a single inductor, based upon a Zack Lau project in the 1990 ARRL Handbook. Not a true balanced design, but the current balun on the 50 ohm side helps smooth t
I haven't figured it out, either. I have an HC-4, but its output is lower than what my Omni V, Corsair, Omni A, and Argosy are looking for. The results are less than stellar reports. My trusty old Sh
About a year and a half ago(?), I was looking for a basket-case radio to fix up. One of the responses I received was for a Paragon that had been zapped by lighting. Unfortunately, I have cleaned out
In addition to the terminating resistors, an efficient broadband balun adds significantly to the cost. Al, K2ZN Looks to be a regular terminated v-beam with some sort of transformer to match it to mu
