yaesu 101zd

[1skywalker]

Can the 101zd be modified like the 101e for am performance on 11 meters? If I cant find a 101 series what other tube yaesu's can be made to perform on am "as well as the 101e"

What do you mean by modified? It's already capable of am operation.

Yup, check the band switch, you should find a 11M selection located at the AUX position or look at the digital frequency display for value within the 11M spectrum

You do nothing to these but talk one em but if it does not have 11 meter in it now then all you have to do is change a crystal inside the radio for 11 meter. Not trying to be an **Censored** but if your thinking that you can mod this radio and end up with a big loud CB radio then you better sell it now before you screw it up. These radios are not that kind of radio!

I was reading where it takes a few mods for the 101e to perform better on am, such as the addition of a wider am filter. I am looking for a101e but haven't found one yet. I found a 102 and a 101zd I just didn't know if they would sound like the 101e series on am, or more like the newer solid state rigs with low level modulation. Thanks for the replies

I have a 101E and the modulation with a D-104 is incredibly clear, now don't get me wrong it is not as loud as my RCI-2995, but the quality is much better. I have many locals I talk with almost every day and they know instantly when I am on the Yaesu. Invest in a good quality Freq counter also. The F model is the desired rig from what I am told, being the last of the series.

Here's the mods for the 101e and the 102 I don't have anything for the 101zd.

I run an FT-101ZD and it DOES NOT have "AM" on it. Just CW-N, CW-W, USB and LSB

Welcome on the CBRT Forum kd4ovm. Then you're like me, and have the early version. The early Yaesu Musen FT-101ZD DID NOT have AM mode, unfortunately for some hopeful owners. There were several vesions often found listed as Mark I or MK1, Mark II or MK2, Mark III or MK3. The latter version had AM/FM and other goodies. Now and then you can buy a separate AM board to upgrade the older version, so I've read. I've seen two for sale now and they weren't cheap. By the time you bought the board and if you paid to have it upgraded, you could probably buy a later model cheaper that already has it.

The FT-101ZD is updated several times during its lifetime, and there are in fact 4 different types, using the same designator. By the introduction in 1979, the transceiver had only SSB and CW, later there was a AM (tx/rx) option, still later the W.A.R.C. bands were introduced, and the last version had it all, including a optional AM or FM board, and Audio notch/peak filter. The later models have more features, so they are more in demand, and are normally higher priced in auctions or on the internet. It seems difficult to see what the difference is between the first and last models because there is not much changed on the front. Fortunately there is a easy way to see at a glance the difference between the various models, the only thing you need to know is the serial number of the set.

Yes you are correct. I love running my ZD and I also have the FT-101F, which is having issues at the moment.
The only thing about the ZD that is starting to be a problem is that it drifts drifts drifts. The digital display is having issues as well and the meter is broken.

Know a good repair shop? HI HI

The Mk I, II and III have AM capability if the AM board is installed. The MK III also has FM capability if the FM board is installed. But there is only one position for AM and FM so only one or the other can be installed and used. If AM is used a wider filter will be needed or the receive audio will sound muddy and a relay will need to be installed to bypass the SSB relay and switch in the AM relay. Been there, done this and it is expensive if you have to buy an AM board and the filter. Inrad still sells the filters for around $115 and good luck on getting a board for under $100 if you can find one. Then there is the relay (though only a couple of dollars) and labor. Whew!!

Just an update. I havent been on the site in a while but I did find a 101ee at a ham fest. 75 meters works great but 11 and 10 the power is way low. Found a local tech that is supposed to be good on the older yaesu's but havent had a chance to get it too him.

[721HACKSAW]

The 101 line of radios were designed for SSB, and perform great there, but on AM you cannot expect the same output wattage. Extended AM use with full power output will greatly shorten the life of those expensive to replace 6JS6Cs.
