Hi Tony,

So, finally it all depends upon from which viewpoint you look at it.

No, it's simple. If the output frequency is lower than the input
(e.g. 1296 MHz in, 28 MHz out), then it's a downconverter. If the
output frequency is higher than the input frequency (e.g. 136 kHz to
3.5 MHz), then it's an upconverter.

Still simpler it is to leave out the up- or down-, and just name it a converter.

That rule works whether you're transmitting or receiving.

In the case of conversion to from a frequency, a transverter does both.
My Tokyo Hy-Power VHF-HF transverter does both.

It converts a HF amateur band to 144 MHz when receiving, and a 144 MHz transmitting signal to a HF amateur band, 3.5, 7, 14, 21 or 28 MHz on
transmit.


Have a nice day,

Holger

True, transverters are usually classified by their transmit/receive (i.e. on air) frequency, with an IF specification (e.g. 1296 MHz, 144 MHz IF - you'd need a 2m transceiver to use this one). :)

How come then the label on the transverter I have says "VHF > HF"?
That's only one side of the coin.

Manufacturers can do all sorts of things. :) I have 2 transverters, one is a "432 MHz transverter", with one port labelled "144 MHz IF", the other is a "144 MHz Transverter" with a port labelled "28 MHz IF". :)

the other is a "144 MHz Transverter" with a port labelled "28 MHz

I have only transverters for 1296 MHz and 10 GHz. Both connect to an
IC-202 for the IF.

On 70cm (432 MHz), I use an IC-402.

Now that I have a FT-763R and IC-7000, I don't need the transverters. The FT-736R is fully optioned up, so I can go to 1296 MHz on that radio. :)

I don't know the FT-763R, so I have to look it up in the ads.

I have always started every activity with homebuilt gear, and later
moved to factory made equipment. For SW (HF) US made, for VUHF japanese,
and finally for SHF, I seem to be stuck with homebuilt again, hi.

This discussion should really have been in the AMATEUR_RADIO or HAM
echoes, to keep them alive.

The same goes for the discussions about Windows. There are two idle
echoes for that, WIN95 and WINDOWS.

It would be nice to involve other people than Sysops, into the
discussions, and keep those echoes alive.

I do really miss a lot of non-sysop friends from those echoes.

GE Tony,

Actually, I didn't have he time either, but I was so bitten by the bug,

I did too, but didn't have the money or facilities (PCB
manufacturing) to build most things.

When I built my first gear (1952), nobody new anything about PCB's.

My first build was a 14-tube double conversion receiver for the Ham
bands. Then a 50 Wo rack mounted CW/AM transmitter.

1955 I built my first SSB exciter, that was a copy of the Central
Electronics 20A, and then a SB-Slicer for the receiver. Then followed a
new transmitter rack that contained an AM modulator that never was
completed, a class AB1 150 Wo PA, and a hefty power supply.

1957 I completed a luggable SSB transmitter, and a receiver, both based
on US surplus ARC transmitters/receivers, intended for a DXpedition..

That year I made made the DXpedition to OH0, as OH2OJ/OH0, with my XYL, OH2QJ/OH0. The Aland Islands then became our new home.

After that I've built a lot of small appliances, and Heathkit gear, both
for myself, as well as to customers that didn't think they were capable.

Printed circuit boards didn't become a part of my life, until sometime
in the late 1960's when I had become active on VHF/UHF.

Was a different world in the 1980s. Component form factors strongly favoured the use of PCBs by then. :)
