I have a multi range 100 amp commercial switch mode psu unit which i
bought on ebay for ?50 sometime ago. Dispite every trick in the book I have never been able to suppress the hash up to about 35 mcs where it dissappears. Excellent unit for service work and running some VHF gear.It was produced for comms work not computors. |

Re: TRA-967
Ron Price
开云体育Many thanks for that Al.
?
Unfortunately the SLA is too close a fit to do as
you suggest so I will have a go at making a clip to attach it.
?
I am still confused by the audio sockets
though!
On my 967 socket 1 has seven pins and socket 2 has
six.
My handset with a six pin plug works in
both.
Clansman type seven pin plugs do not fit as I have
tried the ones from my RT320 but I do not have a Larkspur type to
try.
?
Does anyone know the type I need to look
for?
?
Best wishes,

TRA931 - open to offers
I have a 931 gathering dust. If anybody would like to make me an
offer for it you can either collect it from Ipswich or I can post at your cost. This is not a fully working device .... it has no PA or ATU and the frequency switches have been doctored to allow them to rotate continuously. The luminous stip behind the switch bezels is also missing. When last tested the receiver worked OK and it generated a few hundred mW of SSB on transmit into 50 ohms. Useful for spares, or for what I used it for many years ago - to drive a VHF transvertor. It was acquired quite legitimately as scrap in the 1980s. Has case, but probably not all the fixing screws and an original handset. No battery or power supply (it needs a minimim of 18V to fire up). Further enquiries and/or offers best direct to g4cxt@... rather than via this group. 73 Malcolm |

Re: TRA-967
Belton, Alan
Ron,
Depending on the physical size of the 2.8Ah battery, it might be an option to obtain a dry battery case for the 967 (they still turn up on eBay, new in original packing from time to time, not that expensive), and remove the internal dividers and other bits, then slide the new battery into the case if it'll fit? (With a fast blow fuse in the supply from it, as it would wreak havoc inside the rig if there were a short circuit) I'm not sure if your 967 has the older 6 pin Larkspur socket, or the later 7 pin Clansman type? (Mine is 7 pin, but I've seen 6 as well). If its the 7 pin version, one pin is often connected to the switched supply rail, to power ancilleries from the rig, etc My EMER type info locally gives the following connections, but do thoroughly check first on your rig to make sure: Larkspur 6 pin socket A Microphone live or inner B Microphone shield or outer C PTT D PTT and Headphone earth E No connection (usually!) F Headphones/AF output Clansman, etc, 7 pin socket A Microphone live or inner B Microphone outer (can be isolated for balanced mic inputs) C Switched +ve supply to/from battery (may be via blocking diode) D Headphones/AF output E Earth/chassis F PTT G Headphones/AF output, commoned to D on most rigs, but can feed earpieces separately on harness systems Various rigs do various things with the transmit and receive audio, including the use of balanced mic inputs, and bi-aural headphone outputs, hence the strapped audio lines on most Clansman or later kit Loads of 7 pin audio plugs/headset leads on eBay, stripped off headsets, etc, as well as new 7 pin plugs if you want to wire your own. 6 pin plugs a bit harder to find, probably easier to find an old Larkspur mic or headset and strip the lead off it, again eBay often have this sort of thing very cheaply. Watch out for headsets wired with copper "tinsel" felxible wiring, as they won't take any current, if you try feeding the 967 on tx via it. Best of luck, and Happy New Year Rgds Al G8LIT ________________________________ From: Racal-manpacks@... on behalf of Ron Price Sent: Sun 31/12/2006 13:06 To: Racal-manpacks@...
