[TenTec] Argosy 2

[ROLAND HOWELL]

Hi SteveThanks for replying my shout for guidance on the ARGOSY 2 525d problem that I have.Yes it is the same on all bands.Now on removing the top cover to look at the innards I saw on the mixer board I had 3 x burnt components 2 x 8.2ohm and 1 x 150ohm resistors ( R,s 24-26),these changed as well as the associated small 'C,s, again no difference ,I have followed the path back from the 'S' meter and replaced Q2 and Q11 on the if/audio board, no difference.Went back to the low pass filter ( the odd numbered one 91696 not what is in the manual) and changed the BAT41 diodes in the sensing circuit, you guessed it, no difference.HELP hi hiI have noticed that it seems to be off frequency, I inject a signal of 7.050mHz but seem to get a better tone at 7.045mHz and a small bit of life in the 'S' meter but it still requires a massive input signal in to show any life, the TX indication is spot on.Regards73Snowy

 The manual quotes 0.3uV for 10dB S/S+N typical - that would be-117dBm 
into a 50 Ohm load.

Is it the same on all bands?

>  Hi AllI have an ARGOSY 2 525D, it has a very lazy 'S' meter, requiring some -75dBm from my 2022e to get it to move, it also seems a little deaf, I am not hearing the tone from the sig gen till its at -99dBm, don't know what it should be but most other rigs I have looked at are about -119dBm .The manual shows the original band pass filter board but mine has a board numbered 91696 for which I cant find and service diagrams.I want to repair this before moving it on, I have 2, + OMNI 6 PLUS, + Argonaut 509 and OMNI C ( 3 of) and 1 that I cant remember but it has a digital display with a faulty back light, which is not available any more. If there is a service document available can a kind person point me in the right direction.Thanks, Snowy G0HZE
