Here's what I do Bill. Select PBT mode on the PBT/BW control. Select H CUT on the H/L CUT control. The PBT is now (of course) PBT. The H CUT becomes the BW (bandwidth) control. So the H/LCUT control
Isn't an idling PSK 31 signal a two tone signal? Seems to me it is. Yes, the frequencies are pretty close together but I think it is two tones. Modulate your transceiver into a dummy load and receive
Have you tried a master reset of the microprocessor? I believe the offset between the 5 Mhz VFO and the display changes with modes, CW pitch, etc. Maybe something got scrambled in the NVRAM. Keep us
Are you sure about that Dave? I once had a Omni D series C and a Corsair II with remote VFO and I seem to recall that the Corsair VFO worked OK with the Omni. SEEM TO RECALL is the operative phrase h
The Hercules 444 was high voltage.....something in the area of 50V DC or so. The Hercules II referenced in the eHam link below is a 12V DC amp which requires 12 volts at 80 amps or so. Big difference
Not quite right. Press and hold the MODE button until options are listed in the lower left corner of the screen. Press the button below the option you want and you're off and running. This way you ca
Hmmmmmm.........I don't recall seeing any paperwork in the box my radio was shipped in listing any particular upgrades or upgrade schedule. I ordered, received and paid for a radio that works very we
Randy, I thought for a minute you were going to say that Anderson Power Poles are noisy! Whew! Glad it was power company ...........oh........ never mind! :-) Seriously, I just got a high line noise
Turn MIC and POWER controls to zero (max CCW). Put Omni into tune position and adjust POWER control to obtain desired output from the Hercules. Un-key TUNE. Key rig again with PTT. Speak into mic (in
Jim, I second Steve's suggestion below. There are three steps in getting things set up for what you want to do. 1 - Set the maximum power the Omni VI will deliver to the Hercules II. 2 - Set the mic
Not sure which AGC loop you are referring to but remember, the hardware AGC prior to the A to D converter must reduce any and all signals that would otherwise overdrive the A/D converter. This is tru
The analog (525) Argosy had at least two versions of front end, the 1496 and a diode ring mixer. The change came around S/N 850 plus or minus, don't recall exactly. I have two 525's with S/N's around
OK, I just looked up Kevin's post http://lists.contesting.com/_tentec/2007-04/msg00326.html and see the note about a change effecting the noise blanker at S/N 824. I'll bet a cup of coffee and donut
Ok.......here's what I have. Sorry I did not make it more clear earlier. 525 1096 4 diode mixer (diodes not marked) 525 1188 4 diode mixer MBD101 (I think) diodes 525D 1810 ND487C1 (Argosy II front p
I've tried several different approaches and have settled on switching a resistive pi type attenuator with a really tiny dry circuit DPDT relay. It simply inserts in series with the coax cable that r
Jerry did answer the question very well but let's try another approach. Using a 100 watt max power rig as our base, no SWR foldback, no circuit breaker tripping, the rig can produce a max of 100 watt
