Great post on the details of that RCI case! I remember when that was a big topic of phone conversations with Galaxy and a few distributors at the time. RCI IS repacking some of the old tech while introducing new models. The problem with RCI is still build quality. I continue to see new Ranger...

MSRP in the US will be in the ballpark of $270.00 - $300.00, with dealer cost approaching the $200.00 ballpark. One popular US distributor called me a couple days ago asking my opinion as to whether they should start carrying it, and I had to say no. Not sure this one will catch on very well at...

The part to which Doffo is referring is the AM voltage regulator. Based on the fact that you are seeing proper voltages on the driver/final collectors, and the fact that you do hear the transmit on a nearby radio, I do not think there is an issue with the AM regulator. This is beginning to sound...

I know this is an ancient thread, but there's an HR2600 listing on Ebay for those interested.

Something fairy major had to have happened, but no excuse for not returning customers' radios, fixed or not. I'm going to try to connect with him via QRZ or maybe bump into him on 2 meters, and see if I can find anything out.

Has anyone heard from Mike? I know he's alive and well from his QRZ page.

One other broad-banding trick is to put a 200-ohm resistor across pins 11 and 13 of the SO-42P TX mixer IC. I think those are the correct pins, I'm not at the shop to check my notes. I know its two pins near the connection for L47.

The may seem simplistic, but with the RCI build quality issues lately, look for bad solder joints in the output tank circuit. I've seen a few of these come through that were basically brand new with tank circuit coil connection failures. Any breakdown in the tank could cause the problems you're...

I'll add one more observation to the thread. Many newer exports have separate AM and FM carrier levels. As had been pointed out already, you should use the same carrier level on FM as on AM to avoid releasing the magic smoke.

If you're still looking for a shop, try www.cbshopwhitelist.com for a starting point. Please note that Key's CB may not be a good option right now as the owner is unfortunately rumored to be having some health issues.

I know its an older model, but the receiver (especially the noise blanker system) on the Yaesu FT-100 is quite good.

I used to believe that braided was better than solid because of the surface area. A well-seasoned and well-educated fellow ham in my area told me that a plain old copper wire, the larger the better, works just as well if not better for RF. Cutting the coax can and usually will affect what the...

Bad news. Turns out that the radio had more problems than I thought. After substituting a generator for the VCO, I found that the receiver IC was bad, along with a couple other things. 'Nuther parts radio I guess.... Anyway, thank you for your help!

That's IT! THANK YOU!!!!!

I'll have to double-check the model #, But I DID find it in my SAMs index at the shop. I have the SAMs manual for it, I think #254. It just has no PLL module info.

Ohms law for power when current and resistance are known is Power = Current squared times Resistance. Assuming the 10-amp current is through a 50-ohm load, we then get Power = 10 * 10 * 50 = 5000 watts. Someone please correct me if I'm wrong.

I have a Royce 619 base that needs PLL repair/replacement. I have the SAMs volume for the radio, but that doesn't have any schematic for the PLL unit, just pin-outs. I've been Googling, but no luck so far. Any help appreciated!

This is quite similar to what's already been covered above, but here's what I would start with: 1. Place a 1k-ohm resistor in series with the mic unit's output to prevent possible over-loading of the output circuit. 2. from the other end of the 1k series resistor, I'd put a variable 1k ohm to...

Yes, I'm speaking of Mark Sherman, dba Fine-Tune CB Shop out of New Mexico at the moment. Yes, he's got a good-sounding radio. Yes, he's got skills. But for the love of all things decent, respectable, and even just remotely nice, I am beyond sick and tired of hearing his incessant and...

Thank you very much for your reply! I'm hoping to avoid a scratch-built scenario, but I have the schematic from Sams 94 so it is doable if needed. If it DOES come to having to scratch-build one, I may go for something that uses a basic NPN transistor instead of a JFET.
