Hello, I have sniffer xr7. Can someone help me to make filter1 and filter2 keys on xr71 model?

[GeoMax]

Hi,

"Filter 1&2" is already there... The names are only dirrerent in XR71. I think the name is DELAY and REJECT.

Hi GeoMax
I use the same components as in the schematic R5=2.2k / 1W.
40cm coil =2.7ohm------ 1.2m coil = 1.9ohm

[Ali06]

I don't have any knowledge of electronics. Can you help me install it?

[kt315]

really I do not know SNIFFER XR7, DBP2010, EURODEC, PIMDEC is one schematic or not. can anybody give clear answer?

[kt315]

Ok , fine , can i have a pic
regards

I see LF356 bought from Lemona (electronics shop) is not so fast I waited. even buying in shop you are not be guaranteed. so the pcb will send AS-IS. I have not possibilities and time to sort through them.
anyway you can change the op amp on yours in anytime.

Hello! Sorry for the stupid question (I haven't made PI for a long time). Where is the correct place for the damping resistor? DELTA PULSE device. Thank you!

[kt315]

better inside a coil. but for tuning you can not open clued coil. in DP the damping resistor sets on the PCB. also, you do not need to tune the resistor as DP is working
with 40us FIRST DELAY.

Thank you, KT315! I'll put it on the coil connector.

Hello, My device is delta pulse 2 was working fine.... Today, I tried to turn it on and found it only works in manual tune.
In automatic mode, when I press the reset button, the sound disappears for a few seconds and then returns.
Can someone help me?

[kt315]

if the sound returns its cause is fake LF357, low Slew Rate. your issue now to seek the original.

[anas,ru]

I replaced lf357 with another one in my felezjoo but the same problem. Before a month ago it was work fine.
