1  eHam Forums / Mobile Ham / ALINCO DR-605T VHF GONE on: April 13, 2007, 07:18:05 AM
UGH! The RF Shop says it's the Final for the VHF.  Too expensive for the part-not worth the fix.  The UHF still punches out so I guess it's a single bander for the time being. Transmissions were extremely brief (less than 10 seconds and far apart) so it's very dissappointing.  Even with a bad SWR the rig shouldn't have popped the output if it never had the chance to heat up.  Must've been bad or not properly mounted in production. Oh well.

Wish I saw this reply sooner.  I can see where this could be an expansion problem over time and possibly create the NO VHF scenario.  I'll have to wait and see the result.
  Thanks, Dave

Nothing visual noted.  Going to Alinco.  Will post the repair/resolution when it returns.

Wow: Two fast responses. I see an output device in the Main VHF Unit portion of the schematic.  I'll have to open the radio and check it further.  I'd be surprised to see a Final gone when communications are so short and separated. As far as the solder balls go we're cautious in our shop for these animals.  I call them asteroids depending on whether they originate off the solder machine from a bounce, or after the fact during touchup.  That's all you need is to have one roll in the wrong corner.  
I'll take the case apart and do a visual.

Tnx
Dave

My VHF side just dissappeared off the map.  It still receives.  PA Pwr out is virtually gone....but the UHF is still punching.  Anyone else experience this? Is this possibly a TX diode/resistor problem I've seen in some threads? I have the meters and the tools and perhaps the parts- just need some direction here. Problem is constant from power up.

Tnx
Dave
