In the fifties, my enjoyment and fascination of Amateur Radio was in building, testing and experimenting with Radio. Most Radio 'Shacks' consisted of large units, usually in Racks (see photograph of my 'Shack' shown on the Menu page). I enjoyed having all the 'Knobs, Meters, Dial Lamps, Etc.' which made it look very technical. In the seventies, commercial equipment was made available and a large number of Radio Amateurs purchased Transceivers. I preferred 'separates'; a separate Receiver and Transmitter. This allowed cross-band operation, very useful when working stations in the USA on forty metres. Duplex operation was possible using say, Topband and eighty metres. I was a member of the Bed-time Net, which operated in the late evenings/early mornings using Topband and Eighty Metres. I was a student at that time (1960's), living in 'digs' and operated duplex whilst speaking under the blankets, so as not to make my landlady aware of my operating. That is another story! In the Seventies, YAESU introduced
the FT101 Series of Transceivers which were renowned as being excellent.
Over the years, new Amateur Bands
were introduced; unfortunately, these bands couldn't easily be incorporated
in the FT-101E; major modifications were required.
Looking
around the advertisements, one may at first give up, especially after looking
at 'Limited Offer Transceivers' at £3370. After all, I still have
my 'Home-built Equipment' to keep me active!
The Receiver covers all frequencies
in the range 30KHz - 56MHz.
There is no point giving full details

| The YAESU FT-450
is available as the basic unit, or FT-450AT which incorporates an ATU.
I considered the basic Model, as all my aerials are resonant, and I can simply switch to any band as required. Of course, many Radio Amateurs will already have Aerial Tuning Units they have either purchased or constructed themselves. I do hope that Radio Amateurs continue to make full use of the equipment they already have, and show that they aren't all 'Black Box Operators'. It is easier to build an ATU, than build a Transceiver! It is important to remember that an ATU only matches the Transceiver to the Feeder, it doesn't make non-resonant aerials resonant. Many Radio Amateurs go for the Expensive Transceivers because they like 'High Power', thinking that they will be as loud as Commercial Stations. The best way to put out a strong signal is to construct a good aerial. The Aerial may give many decibels gain, whilst doubling the power output only increases the signal by 3dB; (100W - 200W) or 200W to 400W, another 3dB. One has only gained an 'S' Point, and maybe caused a lot of unnecessary EMC problems, which could have been avoided. Having purchased a new Yaesu FT-450,
I find it an excellent budget priced Transceiver, which is easy to use
and has a good overall performance. Initially, I was disappointed the unit
hadn't got its own Power Supply Unit like the FT-101E, but I appreciate
now that the price would have increased substantially, and also the unit
size would have been much larger. The Unit requiring a 12Volt PSU enables
it to be used Mobile or Portable and allows one to use either a 'Home constructed'
PSU or a Commercial one. Speaking to Radio Amateurs, most are of the opinion
that Home Constructed ones (using a Mains Transformer) are best, as most
commercial PSU are Switched Power Devices, which cause noise on the Receiver.
Some SMPS have an adjustable control to adjust the switching frequency,
allowing the interference to be moved away from the frequency in use.
It is nice to be able to change frequency bands and be able to quickly return to previous bands without having to re-tune, Tuning dial, Preselector, P.A. Tuning and Loading Etc. Having TWO VFO's is also excellent. I use Topband
a lot, and like to operate using Amplitude Modulation (AM). It is convenient
to be able to adjust the Output Power Level so as to ensure one is keeping
within the Regulations for Topband.
The main adverse comment on the FT-450
I have read, is that there is no provision to raise and tilt the front
of the transceiver by using a 'bail stand' or extendable front feet. The
controls at the bottom of the transceiver are close to the table top. I
notice in RADCOM this month, that a Bail Stand is now available as an 'option',
by paying an extra £19.95.
I have read a number of reports on
various Amateur related Webpages about the YAESU FT-450.
An example of a typical advert from a Radio Amateur is as follows: "Like new in the box and everything that comes with it new - This Yaesu FT-450 is 2 months old and has about 1 hour of use. I'm selling it because it is just too much radio for me. Way too many bells and whistles for my taste - This rig has one heck of a receiver, the same one that is in the FT-950! IF DSP, Roofing filters and everything else but the kitchen sink. Puts out 100+ watts on all bands with ease -"
In response, I would like to point out, that the Transceiver can be set up to be 'The ideal Transceiver' to meet ones requirements.
All the 'Bells and Whistles' do not have to be activated. The Transceiver can be used like any other basic Transceiver, and if one later thought, "what a pity it doesn't allow me to do this or that", then a quick glance at the manual would
explain how to programme the Transceiver to do it. One thing I like especially, is that the 'CS' Button can be programmed to inject a 10W signal for tuning up.
On the FT-101E for example, one has to inject carrier manually, making sure that one doesn't 'do the P.A. Valves in'.
Here, it is 'quick and simple', just press the button when in any mode, and the Meter even reads the SWR for you.
When one says 'Tune up'; with modern Transceivers, we only need to tune the ATU, (unless our Aerials are resonant), as all the stages (Preselector, Driver, P.A.) are automatically done for you.

This page will be updated when I have additional comments to make. Latest Info: Stations worked on Forty Metres (SSB) include: WB3HUZ (Virginia); ZL4IR (New Zealand) and VK7GK (Tasmania). The Forty Metre Band is a delight to use in the evening and early mornings, as the FT-450 doesn't suffer from unwanted images! The Aerial used was my Semi-Vertical; details are given on this website.
