Unit 399 might be better but $11 for shipping from Taiwan. the Taiwan has 20 switches for $31.00 and $18.00 shipping so I might do that as I need more than 1. 50 would be good to start off but i'll see how the 20 work. thanks for your time and info

nomadradio thanks for the info I did read that out on the net but thought I might ask if there was an easier way with the MC145106. I guess I will leave it alone and stay with the 10kc mod. Doing the clarifier makes it too sensitive. On the current clarifier mod it goes down about 4 and up...

Has anyone tried or have directions for the pll 8719 or the pll mc145106 for a 5kc jump on the channels like half channels. Not interested in doing the clarifier expansion its already unlocked and just want to do it with the pll if possible. Been looking but not much info for a easy mod (maybe...

Im looking for some small profile 3 pole 5 or 6 position rotary switch. I searched last night and this morning on Ebay and Ali express. with no good results. I need the small profile to fit in a small part box or a radio. Any help much appreciated. here is a picture of a switch but its a 2...

I ordered the same from Aliexpress $3.89 per sw and $2.86 shipping so I ordered 5 sw about $23.25 for 5 sw. Ill get out my meter out and check out the current wiring and see if the switches are the same when switched to a different mode.. again thanks for the help and info

thanks for the info just ordered the 3 position 4 pole thats what is in the radio.

Im looking for a good AM SSB switch the one in radio is scratchy when switching modes. I tried to shoot some contact cleaner inside the shaft but the switch seems sealed/closed. I'm also sure its the same as a Uniden Washington pll 8734/8719. Has anyone replaced with something that will work...

Im sure its the probes as I think I sold my good probe when I sold my spare freq counter did not use. So I ordered a set from amazon 1x and 10x switchable so im hoping the 1x will read with no problems.

Here is the probe im using from my scope. I had another freq counter and sold the probe with it might of sold the wrong one as I have 2 the same. I tried both my probes and same results cane get any reading at tp1 tr13. I will check later today again to make sure and post back here the...

I did find tr13 and thanks for that as the one I located looked like tr13. I did not have a board layout. Still Im not getting the readings im suppose to get for step 3 4 and 5. And again radio is working well. this is the radio from hell Dont know if my in circuit freq counter took a crap...

One crazy Service manual for sure and thanks for the help guys!!!! its a service manual for a trc490 pc-385 board same as a Washington. Steps 9-10-11 just cant seem to find a good test point for my freq counter I marked tr13 for TP3 and if you look the symbol on the pc board is not as the...

The radio works fine Am and SSB receive transmit all work fine. Just cant get the 7.800 readings

Well the problem was I did not have on channel 19 I was over the top of radio and i thought is said 19 but was ch 38. so i was able to get. So I clipped onto r157 TP1 tp1 adjust L20 for 34.92500 and I read 35.1249 for am tp1 adjust L19 for 34.9225 and I read 35.1221 for lsb tp1 adjustct3...

So I decided to align a trc490 ssb radio same as a washington with 8719/8734. PC 385 board radio came with a mb8734 and was changed to a mb8719 with the 11.3258 xtal. In the service manual says the following at TP1 lead of r157. So I clipped onto r157 and tp1 adjust L20 for 34.92500 and I...

Sp5it Thanks for the info I got it to work. On a washington/trc RS490 same radio. Used TP1 R184 and you cant use a long wire. also I have a roll of rg316 coax and used a piece about 24inches long worked great picked up all reg channels and also all the extra channels high and low.. Of course...

can the pictured freq counter be added to a cobra 148gtl and A Washington base? Where is the best point on a Washington base with pll 8734/8719 to attach wire. What is the offset for these radios to be set on freq counter? I just need to do Am channels at this time to monitor. thanks

Nomadradio thanks for the reply and info. I figured that a long cable would be a problem. Im just working on a new channel kit a microchip mod that will expand the 8719 and 8734 plls radios from 26.495 to 28.325. Teststing on a Radio Shack trc490 same as a Washington at this time. Only...

Is there a cheap frequency counter out there that will work on all the cobra president uniden radios that use the mb8719 and mb8734 pll. Looking to wire one internally in the radio and have it sit on top. Of course a cable will be needed to connect inside and then also power the counter. Need...
