Thanks for all the info on setting the off sets will try in a few days after i get a response from the Chinese i got the bad display from

I did make a claim with Paypal and also with Aliexpress in progress. Thing that sucks is a waste of 2 weeks and if I want another gonna be another 2 weeks. Yes their packaging sucks putting that is a plastic bag and the case it was in is like glass it shattered. If it was shatter proof would of...

So I got the OLED counters and 1 was damaged. Those Chinese suck for packaging using a plastic bag to ship it in all the ways from China to USA. Filed with paypal and sent to the Chinese company the pictures. So now I have one in hand for now.

So further testing is that TP3 or R17 on the cobra 29ltd/gtl is the receive 16.270 ch1 and 16.710 ch 40 minus the 10.695. I was thinking about a small relay controlled by the pin 3 keyup pin on the Cobra 29s/25s/ most 4 pin radios. I did not see in the directions on how to set the off set as...

Just wanted to try one in a 29 as I sell a lot of channel kits for these radios and would be great for the 80 extra channels so no channel chart is needed.

I have 2 of these on the way this week and was hoping to put in a cobra 29ltd/gtl Am radio with 80 extra channels. I found a transmit location to monitor transmit but cant find a location for the AM receive I know about the 455Khz down shift in transmit. If there is a spot could someone chime in...

Did you use TP 1 for the madison?

Nomadradio. Is there a section in the 29s that the receive can be monitored I tried and could not find any. thanks

What is the test point location for the 29 ltd/gtl?

So I was probing around a Cobra 29LTD and I see L18 is transmit no receive and I did not find a location to monitor receive so I guess adding 1 of these to a Cobra 29/25 and other AM radios is not a good thing at the moment as you will only be able to get transmit to activate the OLED counter.

if L18 is for receive what point will be for transmit. What about a small relay that the input to the relay common is the counter. And 1 receive point goes to 1 pole and the transmit the other pole. so when u key it will show Transmit and no key it will show receive. You can use pin 3 as the...

I have 2 of these on the way and was hoping to install 1 in a cobra 29ltd that has 80 extra channels. So it will read receive and what will happen on transmit nothing will show? Here is the pdf for the OLED and I dont see any offset function thanks...

On the Cobra 29 ltd/gtl and the Dwight D and cobra 1000. Is there a location on the pc board to monitor the frequency with a freq counter. I know on the Cobra 142/Madisons/Washington and radios that use the MB8719/8735 pll TP 1 which is a resistor on 1 side is a good place to monitor the...

have u found any tweetybirds

Thanks Nomadradio. Again the audio amp that i have been using for the past 5 years works great nice clean audio if the audio amp and the playback module use separate power supplies. The minute i tie them together to share the same supply the playback module audio gets distorted like bogged down...

I tried something like this and still no good. Any better suggestions as i dont think its noise it when the external power supply ground is tied to the module it just wrecks havoc. I ordered some isolated small module 12-5 volts and see what happens or if a better suggestion please im all...

The amplifier is good for 5-12 volt in using the lm386. Been using this amp for 5 years no problem in all my other boxes that use one. Its the recorder board that is getting hit when I try to use an external 5 volt power supply. Using battery supply is ok but an actual 12v supply to the 5v...

The current draw is less than 1amp. To test this im using a Astron power supply and also on my other bench a variable PS dont know the name and same effects battery powered works good but under a power supply power the distorted audio. So it seems to be the 12 volt power to the boards as it...

I made sure all pc board module and LM7805 are all grounded the same common 12 volt in power. Tried all different ways of no ground the 5v reg and the audio amp. So when its working great on battery power I switch wires to the 12 volt in power to the 5v reg and the 5v out pin to power the module...
