Hi I am an OEM supplier of controllers used in the waste water business. I have needed to do a redesign at least 3 or 4 times in the last 10 years because the MPU's or other IC's are fazed out and no longer made by the manufacture. They will usually spec a replacement but it is usually not pin or software compatible.
This is the problem I see with all ham radios that use large scale IC's and or custom IC's. As long as the radio is working I don't see any problem with it lasting 15 to 35 years. But if you get a lightening hit or some part just fails you you be out of luck unless it is just some discrete part like a resistor, capacitor or transistor (even some transistors are no longer made although you can usually find something that will work) Don Brown KD5NDB ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[email protected]> Sent: Saturday, September 29, 2007 6:52 AM Subject: Re: [Elecraft] K rig's longevity? <SNIP> > That last one is a biggie.
