开云体育The stuff under the electrolytic caps looks like glue that was used to hold them in place before they were soldered. Look at the top of such caps. Any convex shape is bad news, they should be dead flat on top. First connect an antenna!?If it was working before try the following. Select one of the four bands. Say band C 4-11MHz. Rotate the MHz knob to centre 7 under the curser with the red lamp off. Rotate the preselect knob to get maximum response. There are numbers there to assist.
Finally use the main tuning dial to show half way between 100 and 200. The set is now tuned to 7.150MHz. Tuning around this figure during daytime will almost certainly bring up strong amateur stations. To resolve the SSB, switch the mode switch to LSB. You
will need safe crackers fingers for this and the fine tune control helps here.?
To tune an AM broadcast station switch to either AM or AM/ANL. In general the ATT and TONE switches should be in the centre position.
If none of this works you may have a problem!
Best of luck, they are remarkable receivers.
