Pye Telecom PF8

In the end, we did not sell that many of these at Pye Telecom. It took a lot of time to get to market and, really, it was not worth the effort. It has some innovative ideas for its time: it used a multi-layer PCB (a first at that time), a DC-DC converter (what a nightmare!), an internal antenna, looked before its time like a cellphone, no external parts to break,etc..

It featured on TV in "The Professionals".  

Some were converted to 70cms. They are rare these days and I do not have one! Your best bet is eBay. There is a PDF manual on my website.

PF8 Manual - NOT amateur radio

Many will remember this famous transceiver from the 1980s. It was made famous by featuring in the TV series "The Professionals". A copy of the PF8 service manual is available here.

Pye Telecom PF8

Many years ago, I was involved in the design of the PF8. In the end, I do not think too many were sold. The antenna was my design as well as the TX audio.

It gained fame as it was used by Bodie and Doyle in the TV series "The Professionals". Style wise it was well ahead of its time. 

One has appeared on eBay untested . The last time I looked it was £225!! I should have kept one!


These are rare these days, but some were converted to work on 70cm. If you can find one, good luck!

Pye PF8 - NOT amateur radio

Back in the 1970s, I was on the design team for this revolutionary product. In its day, it was "ahead of the curve". 

It had an internal antenna, 1.2V rechargeable batteries and a multilayer PCB. From bitter experience we found that the things that got broken were things like antennas, rotary controls etc. So we avoided these in this design. In its day, it was iconic. Some went on 70cm. These days, they are very hard to find.

See https://sites.google.com/view/g3xbm4/home/vhfuhfmicrowaves/vhfuhf-commercial-rigs/pye-pf8 . There is a PDF copy of the handbook linked on the site. Any issues, contact me and I shall send it to you.

The DC-DC converter it used was a nightmare.

Pye PF8

Many years ago I had the privilege of working on the design of the Pye PF8. My bits were mainly the TX audio and the skeleton antenna. The PF8 is rare now. Some were converted to 70cms use. I created a webpage with some useful links.

Pye Telecom PF8 transceiver

This radio, that I helped to design, has gathered a cult status over the years. It was the radio used on the UK TV series called "The Professionals".

Some have been converted to use on 70cm. Before anyone asks, no, I cannot help you find one!  They are rare these days. I do not possess one and neither do my old colleagues.  My best advice is keep your eyes skimmed in case any appear on eBay or at rallies. Looking back, we did not sell that many. We made more pagers in one night, than the total number of PF8 units sold.

That was the trouble with PMR radios. Once we faced significant price competition, we just could not compete. These days you can buy UHF PMR transceivers for a fraction of the price 40 years ago.

On my website is a .pdf version of the manual.

In its day, way before cellular radios, it was quite ground breaking.

Pye PF8 transceiver

In its day, this was a "state of the art" transceiver made by Pye Telecom. One of my early jobs was being part of the design team for this. We had all sorts of issues with the DC-DC converter noise. On my website is a PDF of the manual which may help some who convert these to 70cm amateur use.

They are quite rare and hard to find. Before you ask, I do not have one and do not know where to find one! Your best chance is on eBay I guess.

PF8

Over the years, several people have asked me about this radio. Back in the 1970s I was involved in the design team.

It was made famous in a TV series called "The Professionals".

The PF8 manual is also available as a downloadable file at the bottom of my page on my main website.

Pye PF8

Many years ago I was part of the design team working on the PF8 transceiver. In its day (before mobile phones) it was a radical design and probably "ahead of the game" as they say. It used a radical internal antenna (a skeleton slot) which I designed along with the TX audio. In those days we had no real competition and it took a long time to overcome the noise issues with the DC-DC converter. It was the first Pye Telecom unit to use a multi-layer PCB. It became famous as the transceivers used in the TV series "The Professionals". PF8 units are very hard to find these days, but some have been converted to 70cm amateur use.

Pye PF8 on 70cm FM

The Pye Telecom PF8 was, in its time, a very futuristic handheld UHF transceiver. They are very rare. I was fortunate to be part of the design team a very long time ago. I was responsible for the TX audio and the antenna which was quite novel. At the time Sir Clive Sinclair asked me for advice!

The PF8 was made famous in the UK TV series "The Professionals". If you can find one, they can be made to work on 70cms. Finding one is very hard. Before you ask, no, I do not have any. TX power was 500mW.

Pye Telecom PF8 - NOT amateur radio

Some years ago I was professionally involved in the design of this innovative transceiver. I am sure I mentioned this on the blog not too long ago.

Some people managed to find rare examples on the secondhand market and converted them to 70cms use. They are hard to find as not that many were made.

Pye PF8

See https://sites.google.com/site/g3xbmqrp3/vuhf/pf8 .

In my younger days I was a design engineer with Pye Telecom and one of the projects I worked on back in the 1970s was the Pye PF8.  In its day this was a very novel transceiver, with few controls to get broken, an internal antenna and a DC-DC converter so it ran on a couple of rechargeable batteries.  I was responsible for the antenna and the TX audio but was also heavily involved in debugging the many issues we had.  The product became world famous as Bodie and Doyle used the radio in the TV show "The Professionals".  Not that many were sold and on the second hand market they are very hard to find. I know some have been put to use on 70cms. They worked well in the end but they were a nightmare to work on at the time.

It was around this time I met Clive Sinclair.  He was interested in compact antennas for his little TV and was interested in co-operating  on RF ICs. Neither happened but I was flattered he had asked me for advice!

Pye PF1 and PF8 handhelds

I've justed added a couple of pages to my website on two Pye Telecom PMR products I had involvement with in my early days in the development labs there.

See Pye Telecom PF1 Handhelds and Pye Telecom PF8 Handheld

For far more information on Pye Telecom see the website http://www.pyetelecomhistory.org/

Incidentally there is a drive to set up a permanent museum of radio history in the Cambridge area in which Pye Telecom products would be featured. £30k is needed to get this project off the ground. See the Pye Telecom History pages for more information on this project.
