    Thank you! The clerk didn't remove the security tag, and I live far away. This was the first answer about removing the tag that actually made sense. Though mine looked different, this basic method worked!

    I tried to send it online to Officeworks so they can put it in a binder but it says the file is password protected, some further investigation show me I can open it and print on my own printer but I have no copy permission so I can’t upload it to an online service. I could put it on a flash drive and take it to the counter as long as they print directly and not upload it into their program (I’m making assumptions here). A Canon camera manual got the same error message.

    My Cobra 18 wx st has an issue where the weather works loud and clear but it will not receive or transmit any CB. Could I somehow mail this to you and pay to have it repaired?

    The Jfet I believe crosses to a NTE 133 SGD pin out may be different. The other transistors are all 2N3393 . I also think once aligned a 9v battery would be fine in place of the 8.4 .

    Hi Peter. I was given a TS430. Deceased estate, It was left in a cold damp basment before I got it. It starts OK, lots of noise from the speaker Desplay reads OK, PROBLEM, the Mode selector will NOT work and is stuck in FM mode. Touching the other mode buttons gets a slight change in noise light shows up in that position, BUT jumps back to the FM mode, when button is released. I tried the relay cleaning trick and did a reset, to NO avail . Looks to be putting out full power and meter needle moves to full scale into a dummy load. Any ideas what to look at next please.

    I would like to second that it is important to let your radio warm up for 30 minutes or more before doing this adjustment. Mine drifts a bit from cold to warm. My radio was not dead on from the factory. It was probably off 20 or 30 cycles per second. Thanks for the video!! Robert K5TPC

    Kindly advise: I extracted the output filter board of a TS-430S to work on it. Issues: 1. Intermittent low rx (probably "dirty" relays). It appears they are all sealed (except the tx/tx relay). I tried using a "wetting voltage" as described in a Kenwood service bulletin, but there is still intermittent loss of rx, especially on 10m. 2. One of the inductors (L41) is shorted. 3. How do you test a diac (D18)? (It reads short circuit in both directions.) Apparently it is for overload/surge protection. 4. The S meter reads extremely low. I failed to recalibrate S9 (even with the trim at maximum, it doesn't reach 9).

    I just downloaded and installed Chirp for the 1st time. It is version 20240224, and it does NOT have a "detect" option for the radio model. I'm trying to use it with my 7610 on Com3 with a standard USB cable that works with my other software. I made sure that Omnirig was not running. The download function flickers as if it's going through the motions, but does not read the channels from the radio.

    Why is it not good for the solid "dot" on the oscilloscope to be one the screen too long when you are in the "trap" mode? Sometimes my old oscilloscope malfunctions and the dot is on there for a long time before I notice it's loose contacts in the switches and I have to move the switch to get the sweep line to come back, lol. maybe this will cause damage to my display screen?

    I don't see the two tones that you are using, I'm thinking that one of the tones is 1000Hz? I did a fast online search and it shows 700 and 1900Hz here is the quote "The standard two tone test applies two audio frequency tones to the transceiver microphone from a quality sinusoidal generator at approximately 700 and 1900Hz. The exact audio frequency is not critical other than they cannot be harmonically related and should be sufficiently separated with in the audio band pass." So I guess you could play around with the two frequencies in this case as long as they don't match in "harmonics" and that would most likely be visible on the scope monitor as a merging type image.

    In my area we have multiple repeaters with the same frequency and differnt CTSS tones and I have them programmed as seperate memory channels with the frequency/CTSS pairs. Put another way, in my current configuration I have multiple channels and there may be the same frequency that has different CTSS tones. Currently the only available options I see and have set each channel as: Tone Mode = TSQL Tone Squelch = CTSS Tone frequency# Speaker Mute = Tone/DTCS (I don't use Optsig) For the radio I have the basic setting SC-MOD = Off Currently when I start memory scanning, the radio will stop scanning on the first channel that has a carrier detected (independent of the associated CTSS tone received) and the squelch will also not open (can't hear the transmission) if the CTSS doesnt happen to match. What I want the radio to do is scan memory channels until a channel frequency AND the specific CTSS assigned is received and then to resume scanning when the carrier with tone stops transmitting on that channel.

    I have a Tempo One and need to troubleshoot the power supply (don't even know if the RADIO works!!) I powered it up on a variac, but as soon as I got to 50 volts, one of the big honking resistors on that resistor board burned up!!! Do you have a video on troubleshooting/repair of the AC 1power supply? Anyone in KZread land know what I need to do next?? Is it fixable, or something that's pure unobtanium?? As common as these radios seem to be, there's NO VIDEOS ON THE POWER SUPPLY???
