I have now completed my modification by installing the replacement power
module. The changes required to fit the new module are very simple, it is
just a matter of removing 2 links and one inductor and installing one link
and two resistors, plus the module.
Power output of 20W was achieved
Also see http://www.mike-willis.com/XV70_Pt1.htm for some alternatives. This
document is not finished yet, I still need to document the power amplifier
conversion though this is effectively already documented in the most recent
XV50 manuals.

Specifying them is easy, getting them is more difficult. The problem is the
part numbers used by Elecraft do not relate to something you can actually
order. We need to find out what the actual part numbers are and order the
coils with the next lower inductance.

We could try asking Elecraft for the part number of those components - I
think they are a little busy right now, but give it a month or two

Thanks Allan,
I have managed now to get to an output of about 0 dBm from the driver stage.
I have not got the power module in as I doubt it will work on 70MHz. I will
replace it with one that does. The 0 dBm is a little disappointing but I
know why and am working on fixing that.
The harmonic
I am working on it. My plan is to make as few changes as possible while
maintaining adequate performance. This will be a compromise but should make
it easier to modify existing units.
I will put the instructions on my web pages (www.mike-willis.com) when
ready. I have done the design work but I
I too would be interested in buying an XV70, or a XV50 kit and applying mods
as part of my build.

I am making good progress. I managed to find an XV50 locally to do a trial
conversion. I will end up with two but perhaps someone will want one of
them. It has taken 5 hours because I was also writing the documentation
which will be on my web pages.
So far, I have managed to get the receive side
Well, I'd be doing this on a new unbuilt XV50, so if changing coils is good
and someone can document what that change is ...
I'm quite capable of assembly, but not of design.

Hi...
Please : Give us the XV70 !!!
Looking all around the world 4 mts transverter is a dream, Monaco, Portugal
(+ Azores ) and other countries are open now on 4 mts..
When we found a dealer there is no more this, no more that, we have to wait
til October etc. At the end of the story it is a

think they are missing an opportunity to create a successful new product for
a very minimum of RD effort. I think an Elecraft “XV70” would do well
Yep Allan... I'm here ..
ready to build a 70 mhz transverter if there is one from Elecraft ( with
components included ) !!!

I have been so pleased with my XV50 that I have just started using on
6m, that I would jump at the chance to buy an XV70 to be QRV on
70MHz. Please Elecraft, think seriously about producing one.
