1. [TenTec] Keying Problem with Paragon 585 and Giehl Chip V27 (score: 1)
Author: W4EF@dellroy.com (Michael Tope)

Several weeks ago, I described a keying problem with my Ten-Tec Paragon I (e.g. model 585) whereby the rig does not sequence properly when T/R switching in the CW mode. The problem only occurs over a

Has anyone run into trouble with the keying on the Paragon I. On mine, it gets confused when I am trying to key it at between about 20 to 25 wpm and do a frequency offset (rit or split mode) at the s

I am using an external keyer. In fact there is no internal keyer in the Paragon. The problem appears to be with the T/R switching firmware. When switching between different transmit and receive frequ

Yes, in fact I was already through the PLL problem about two years ago. First it was the low frequency VCO that started phase popping (noticed it on 75 meters). Then later it started with mid range V

Bill, I have a Paragon I here which oddly enough I hooked to my spectrum analyzer the other day (I wanted to set the power level to circa S9 so I could check out the key clicks with my Drake R4C). An

Hi Bill, I checked my Paragon tonight with the VFO set to 1813.00 KHz. The high-level close-in spurs that I saw on the 7MHz spectrum are gone with this setting, but I am still seeing low-level discre

Yes, I agree. As long as you tailor your bandwidth to band utilization (wide when the band is empty, narrow when band is crowded), then I don't have any problem with wideband SSB. After all, nobody i

A loop thru for an external linear amplifier would be nice too (this can be a major source of TX distortion). Seems like you could unmute the receiver by an appropriate amount and then downconvert th

Its a handy feature if your keying an amplifier with a slow T/R relay. Contest logging programs like TRlog close the PTT line a few milliseconds before the CW starts. This can give a slow amplifier T

I would have to agree with Yuri on the importance of #5. I operate from a club station that is setup for Kenwood radios. If I plunked down $3.5K for an Orion, I would probably want to drag it over an

Actually what Sinisa is suggesting is not just mental monkey spanking, it is a very good test. If you don't hear an increase in background noise when you connect your antenna, your receiver quite lik

Wait a minute!! Don't forget that we are the authorized radio service, not BPL. FCC rules don't protect BPL from interference that it might suffer in the presence of LEGALLY AUTHORIZED RADIO TRANSMIS

If you know the power density (in watts/meter^2) of an incoming plane wave, effective aperture is a very useful concept for determining the amount of energy captured by a receive antenna. In other wo

Yes, there is antenna gain measured in dBi (dB isotropic) and then there is dBmb (dB in mind of beholder). As you suggest, the latter usually involves large DXCC totals and wet pasta :) 73 de Mike,

Actually Sinisa, you just made my point. If you know the effective aperture of the receive antenna, then you can do the calculation of received power straight away. If on the other hand you know the
