Some photos of my unit during its restoration.

It is, after repairing the mains transformer, trying to work. I have strange results from the R.F. modulator, and better results from the video output.

The previous thread has SG3 and SG6 pdf duplicated. I am unable to delete them.

Also, PYE TMS 3 pdf is a far better scan than tms three pdf.

Mods, can you remove the duplicated pdf on my previous post and remove tms three on this one as well?

Can you please rename this title so that it follows on from my previous Pye telecom thread?

Thanks, Rob

Of note, the 1.5GHz SG6 signal generators that I have seen all have decent HP step attenuators within.

The earlier manufacture small (tms, if gen, tm1, vhf & uhf reflectometer) test sets were blue and in a heavy case. The later ones were in a black aluminium case with a buff colour front panel and considerably lighter.

The SG3V and SG5U were the mainstay sig gens for many years on vans and in service depots. Mine was used from 1978 to 1990. They withstood a lot of bumping around. However, the spurious outputs a few tens of megs off carrier were at a fairly high level. Possibly only 30 or 40 dB down from memory? The output attenuator was a piston type with a 50 ohm termination resistor on the pick up loop. Easily burnt out with a tx feeding in!. Field replaceable with a 51 ohm resistor.

Hope this is of use?

Rather to my surprise the circle generator is all analogue. Very little logic, all original 74 series TTL.

It used an HLY7006R IC, long since obsolete and now, 'unobtanium'.
