Was in the shack earlier this morning and got a call from a friend of mine.
Said he was just leaving the Maysville Hamfest and wanted to know if I was going to be home. Said he had something for me.

I work on a lot of his equipment.
When he got here he started showing me some of the gems he picked up.

A very mint SB201. This thing looks great!
A heath kit 3kw tuner that requires a little work
A Icom VHF all mode. (older don not remember model)
A few D104 mics
Frequency counter
Browning Mark 3
A clean looking 11 meter amp. Never seen one so dont know much about it but was told it was set up for 10 meters.
A Dak mark 9 LOL

And know the good stuff.
He pulled out 2 Yaesu FT-101's. One E and one F.
The F has a few knobs missing and he was told it was for parts.
He gave me both of them and said merry christmas.

I like to dropped. Been wanting one of these for quite some time now.
Of course I thanked him and he said have fun!.

The F model does recieve and puts out about 2 watts. The E comes on but no recieve of TX. They are not the cleanest rigs I have seen but also not the worste.

So now two more restore projects on the burners.

Me so happy.

Why am I thinking of the words "lucky" and "SOB" right now? :biggrin:

There were not too many of the "F" models made. They were the last in the 101 series and had all the latest and greatest upgrades available. I would put my time and effort into restoring the 101-F first. :thumbup:

As for the 2 watts from the F model, check the driver tube as well as the finals and make sure the grid switch is not turned OFF. That allows just the driver power out to the antenna to operate a transverter. (I think the 101 has that function.I know my Kenwood TS-820S does.)

That is because "lucky" and "SOB" goes together:thumbup:

You know I have not even thought about that. Now thats is a plus

I have to dig on that. You may be correct.
Oh, did I mention I have the user and service manuals that came with them also? How lucky is that? :tt2:

Feel like I won the lottery :)

Now have to find that Yaesu paint code again.

woohoo.gif

Cant help myself. :biggrin:
Now if I can just get the time to work on them.

I need to get out in the shop and clean up. Make some room and re-arange the radio desks. Now I have to get my Hygain 6HDXX up and put up a few more dipoles.

To much to do.

Probably want even be able to sleep tonight.

Radio Tec thats a first that i heard about hybrid radios . I know Tube radios and Transistor radios but this is a first to me but you learn stuff every day lol . You can call me CJ a Ham Tec .
 
CJ, there were a lot of hybrid radios made in the 70's and early 80's. Solidstate design was pretty much the answer to everything back then except an economical way to produce clean power levels in the 100 watt class range. The answer was to make the entire radio solidstate except for a low power tube driver stage and a high power tube final stage. Yaesu had many radios in the FT-101 series that had a 12BY7 tube driver stage and a pair of 6JS6 tubes in the finals while Kenwood had a number of radios in the TS-520,820,and 830 series that used a pair of 6146B's in the finals. They are some of the best radios either company ever made prior to the latest and greatest digital wonder radios. Actually in some cases they even outperform the basic functions of some of these radios. Here are some classic hybrids of which I would be proud to own any of them. I do own the TS-820s series. :thumbup:

Nice radios . Back when he had a ham outing with Generals and Extras there and hear them on 7 mhz and it was amazing what you could do on 7 mhz and go from Florida to Texas .

I was thinking about this today.
I have not had any time to work on these.
But last night I looked in the back to be sure the Acc plug was in the rig. The 101 does not have a switch on the back other than the front panel heater switch. If the plug is not in it will not produce power.
I do remember seeing a RCA jack hanging out the back of the plug. So going to check that out tonignt.
 
Last night I pulled the ACC plug off the F and put another one on.
Sure enough I got full out put on 40 and 80 meters. Less thn 20 watts on all other bands. The S-meters works but not in PO, IC or ALC. So got to trouble shoot the reason power is down on other bands and the meter circuit.
 
Sounds like it's on the road to recovery already. :thumbup1: I wasn't sure about the Yeasu's having the grid cut-off switch like the Kenwoods do but it was worth a look.It's always nice when a "broken" radio is easily repaired. When I bought my TS-820S it came with the external vfo VFO-820 as well. The seller told me up front that the external VFO did not work and he thought that he blew a transistor in it when he unplugged the interface cord with the power on and saw a small spark.The radio worked great with the internal VFO but needed the interface cable plugged in to work unless I jumpered the jack on the back. I got the radio home and opened up the VFO and while I was poking around I found a bad connection inside the cable where it connects to the jack. He must have broken the tiny coax cable that carries the VFO signal back to the radio.It was a pain to solder as it was so tight but after a couple minutes I had a fully operational external VFO allowing me to work split. :thumbup:
 
Now thats pretty good. Strange that things will break and folks will sell it . Most today lack the know how when it comes to this stuff.
Glad that one worked out for you.

I got on 80 meters and was tuning around and heard a couple of guys chatting. After they finished I threw my call out using the F. One came back to me and said I had good audio and wanted to know what I was talking on. He was in Texas.

If it sounds good now I wonder how it is going to sound when I get it fixed. Not sure how much bias I have but I did turn it way down.

Not going to get much done this week end. I have to work in the morning and repairs Saturday. I am suspose to be on a week lay off next week but a guy wanted to switch with me. We are required to take a week of lay off a month untill the end of the year. But one line is running and they work a lot of OT. So I will be working. Oh well.
So much to do so little time.
