GENERAL DESCRIPTION

Your SOMMERKAMP TS-680EDX transceiver has been désignée! for continous

heavy duty mobile and base Station application.

It c n be oper ted w ith microphone nd intern l spe ker or h ndset, spe ker/

microphone combin tion, telephoneset incorpor ting utom tic voice oper ted

tr nsm it/receive switching, extern l sélective c lling w ith utom tic nswer

b ck nd m ny more.

GENERAL

The tr nsceiver is designed to op er te fro m 13.8 Volt DC powersupply s

b se or mobile st tion. It's str ght forw rd 80 ch nnel c p bility llows it to

oper te on ny ch nnel w ithin 26.965 nd 27.855 MHz.

RECEIVER SECTION

The receiver section is designed to receive mplitude modul ted (AM /A3)

sign is in the 26.965 to 27.855 MHZ. (11 m eter) citizens b nd .

The unique com bin tion of low noise Field E ffe ct Tr nsistor (FET), double

conversion, com bin tion of mech nic l cer m ic, nd L/C filte rs, fu lly uto

m tic noise lim ite r (ANL) nd h ifi qu lity spe ker m plifier w ill give you

exception l réception qu lity in this fine piece of equipment.

In ddition, the bove com bin tion of the l test technology provides you with

se nsitivity nd unw nted sign l rejection nd noise suppression v il ble

previously only in sp ce nd m ilit ry com munic tion equipment.

The power supply of the receiver RF. IF. nd oscill tor section is st bilized

by n extreme sh rp cu t-off Zener diode to obt in the high sen sitivity nd

unw nted sign l rejection. The fu lly utom tic sériés gâte noise lim iter, which

virtu liy cuts o ff the udio output during ignition noise puises, is defe t bie

to m ke even the we kest sign l udible which otherwise would be eut o ff

by the threshold level of the ANL switching diode.

The high squelch sen sitivity is chieved by using seper te squelch detector

nd sw itching circ uit w ith c refully b l nced hystérésis. The tr ns-

form erless h ifi qu lity udio power m plifier w ill drive ny lo d between 8

ohms nd indefininite such s intern i spe ker or extern l spe ker/microphone

TRANSMITTER & MODULATOR SECTION:

The tr sm itte r section is désignée! for continous he vy duty tr nsm ission of

m plitude modul ted (AM /A3) sign is in the 26.965 to 27.855 MHz. (11 mete'r)

citizens b nd.

The tr nsm itter consists of Ph se Locked Loop c ircu it nd n one-cryst l

controlled oscill tor, of which output is synthesized in d ss B mixer, followd

by double tuned filte r, d ss A B I buffers, nd highly efficie nt collector-

modul ted d ss C driver nd power output st ge, coupled by séries nd pi-

m tching filte rs to the ntenn j ck.

The modul tor consists of n input udio filte r, ALC m plifier integr ted pre-

nd power m p lifie r-- nd m odul tion tr nsform er. This gives you the lowest

possible modul tion disto rtio n nd up to 100% modul tion.

The input is designed for 500 ohm dyn mie microphone or 32 ohm spe ker/

microphone com bin tion w ith 1K ohm resistor in sériés.

RECEIVE/TRANSMIT SWITCHING

The re ceive/tr nsm it sw itching is done by single pole, single throw switch

in the microphone nd combin tion of NPN nd PNP switching tr nsistors.

METER

The combin tion m eter provides you w ith the following functions:

During receive m ode..................it indic tes the incom ing sign l strength.

During tr n sm it m ode

.............

it indic tes the output power.

For norm l oper tion, be sure if the RF GAIN knob is pushed.

For checking the SWR of your ntenn , pull the RF GAIN knob, then the m eter

w ill function s SWR meter.

MOBILE INSTALLATION

Mounting br cket nd screws re supplied for mounting the tr nsceiver under-

ne th the d shbo rd. Microphone h nger nd screws re lso supplied. For

ele ctric l connection, firs t m ke sure th t the tr nsceiver is turned off.

Connect the red wire to the ACC term in l of the ignition sw itch or + term in l

of b ttery nd ground the bl ck wire to the ch ssis of the rehicle. The bl ck

wire should be grounded s short s possible to m inim ize noise interférence.

This tr nsceiver is designed for use with the neg tive ground system.

50 OHM ANT

Connect the ntenn pług to the ntenn j ck with n SWR-Meter inserted

into the ntenn c bie.

Connect the microphone to the microphone j ck.

Switch the tr nsceiver ON.

The receiving, m eter nd the ch nnel l mp, sh ll lig ht up.

Turn the squelch control to min. (ANL OFF)

Turę the Volume control to m x. Until you he r rushing sound from the

spe ker.

Swith the ch nnel selector to CH. 1.

Push the tr nsm it button on the microphone nd check the SWR of your

ntenn w ith the SWR-Meter im m edi tely by pulling the RF GAIN knob.

The SWR must be less th n 1 to 2. Do this w ithin 3 seconds, bec use if the

SWR is higher th n 1 to 2 it is very lik ely th t the tr n sm ittin g tr nsistors

w ill be d m ged if you oper te the tr nsm itte r too long w ith ntenn

h ving too high SWR. Also re d c refully the recommend tions on

ntenn s

NOTE: In c se the SWR is too high, the Autom tic protection circuit w ill

sw itch off the tr nsm itter.

If the SWR is less than 1 to 2 continue Checkout? if it is more than 1 to 2

repair or replace your antenna.

Check th t the m eter needle is ne r the red m rk during tr nsm itting. T lk

into the microphone. The m eter needle sh ll move little . Rele se the tr ns

m it button nd switch the ch nnel selector to ch nnel 1,2 etc. until you

receive st tion.

W it until this St tion stops to tr n sm it nd turn the Squelch control slowiy

to m x. Until the b ckground noise ju st dis ppe rs. When the st tion St rts

to tr nsm it g in, you w ill he r this st tion, but you w ill not he r the b ck

-ground noise during non tr n sm itting periods.

OPERATING INSTRUCTONS

The tr nsceiver is re dy to oper te when it is inst lled w ith n ntenn

properly connected. Note th t the com munic tion r nge diffe rs depending upon

the environment where the tr nsceiver is oper ted.

You m y re ch 30 or 40 kilom eters where no obst cle exists, but the r nge

m y be lim ited to 5 or 6 kilom eters in cities where m ny high buildings

disturb the com munic tion.

1) Turn the set on by switching the LOW CH-OFF-HIGH CH. sn p switch to

the desired ch nnel r nge nd the ch nnel di l w ill be lighted. Turn

the volum e control clockw ise to incre se the udio sound. Note th t the

volume control knob is only for djusting the udio volume, not to in

cre se the tr nsm ittin g power.

2) Set the D ELTA-TUNE for best réception.

3) Turn the squelch control clockwise until incoming noise is elim in ted. Do

not turn it excessively s the sen sitiv ity m y be reduced.

4) Turn the squelch control counter-clockwise to switch o ff the ANL

(Autom tic Noise Lim iter).

5) Turn the RF GAIN control to the m xim um clockwise position.

6) Turn the ch nnel selector knob to the desired ch nnel.

7) For tr nsm itting, press the button on the microphone nd spe k into it

norm lly. Rele se the button for receiving.

METER

The m eter re ding indic tes the sign l strength t receiving, nd functions s

n output indic tor t tr nsm itting, nd the m eter pointer should be w ith in

the red zone under the norm l conditions.

CIRCUIT PROTECTION INDICATION LAMP

The l mp is on when the ntenn is mism tched, nd the tr nsm ittin g c ircu it

w ill be eut o ff. This L mp is loc ted underne th the ch nnel lens.
