Denpa MZ-22 Also Fail

Turns out the design of the Denpa MZ-22 is just as bad, or rather it is even worse.

The head was hard to get to...while less prying, there were more screws. Also the cable web inside the head prevents access to the solder points for the battery.

Worse the battery is upside down, so I won't know what kind of battery until I remove it.

It crossed my mind that perhaps I'd find out how much it would cost to send off two radios to get batteries replaced, etc. But, as I was putting it back together, I wondered about the funny scorch marks on the underside of the lid.

Apparently I burned out some transistors on the board years ago when it was my packet radio....not sure if worked the last time I used it...so it might be fried. My fuzzy recollection was that I had some kind of issue with it, which caused me to go back to using my HT for packet. So, that's probably why I was having issues with it.

I wonder if new radios are better or worse with this. I suppose the fact that virtually all mobiles these days have removable/remoteable heads might lead to easier to replace batteries.

Just not sure when I'll get a mobile rig now.

Yaesu FT8000R Design Failure

Some time in 1997, I acquired the Yaesu FT8000R dual band mobile radio. I hardly used it, mostly just listened the local repeaters and the ambulance channel probably. There was probably only one or two public service events where I actually got to talk on it.

But, then I totaled the car in November 1997. And, I barely got the radio out when I went to visit the car in the salvage yard.

I moved away from Medicine Hat and boxed up all things Amateur Radio and moved. I left most of the big stuff (antennas) at my parents place, when I later moved down to the US. And, I already talked about that story.

Now that I'm back doing Amateur Radio stuff. I've been slowly going through boxes digging it out. There might be the opportunity for some public service work, though that wasn't what led to me digging for the FT8000R.

There's the upcoming 10th anniversary of the K-Link system coming up, and the local K-Link repeater requires tone access. Also, I apparently it is located somewhere that I can't work using my HT at home.

So, I got to thinking that I should have a base 2m (at least) radio. Of which I should have two in my collection somewhere. Since, I need tone....that meant looking for the Yaesu, because the ICOM clone doesn't do tone or much else...it was cheap from a hamfest, and being sold as a packet radio because it lacked things like a microphone. Which is fine, because I was getting tired of heating up my HT for packet radio....

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
