I didn't really find anything on amazon, but here is something you can get for less than 100 dollars that should work for a beginner. https://www.ebay.com/itm/286597425513?mkcid=1&mkrid=711-53200-19255-0&siteid=0&campid=5336136228&customid=&toolid=10001&mkevt=1 so, this will allow you to input...

HavaV10, Do you have a signal generator? if so, there is an adjustment you can make (well you can make the adjustment either way, but the sig gen lets you confirm that you haven't lost any significant sensitivity). Ranger radios all have this issue to varying degrees and it has to do with how...

the service manual on cbtricks.org for the realistic TRC-450 should have an IC voltage chart in it, where you can see the correct voltages of each pin on the MB8719 and UHIC-007 vco chip. measure the voltages on both IC chips and let us know what you find. pin 10 on the PLL might be different...

the absolute cheapest RF sampler you can build? well, it may not be fancy, but you can wrap a few turns of insulated wire around the wire going to the antenna jack of the radio and attach a scope probe to each end of the coil that you made. LC

you should not have to have your clarifier turned off center in order to receive and transmit at the same freq. if you have to, this means that your clarifier is still locked and you haven't adjusted the TX trimmer resistor correctly. when aligning this board, specifically the PLL/VCO section...

wait, is the US version of the washington modifiable for extra freqs? i thought only the European version was modifiable. LC

the "1 khz tone SSB tuning" trick should only be used on the IF section (7.8mhz). the 34 mhz pll/vco section should be tuned using a freq counter at the TP. this method works pretty well and the reason you can't just set those cans for exactly 7.7985 and 7.8015 is because the crystal filters...

this is for the LT but its the same board: https://cbtricks.org/radios/uniden/grant_lt/ also the same as the 148GTL. LC

HavaV10, You're most likely not going to have the test equipment required to get VR2 set "correctly" but you can most likely just turn it to about half way and you'll know if this was your issue. the easiest way would be while listening to a SSB signal that is strong enough to cause the...

thanks nomad! i guess i was confused about how much idle current to use for a four mosfet setup. You stopped at 80mA which tells me it tried to take off on you above that level. Can you remember what the gate voltage ended up being at this level? also thanks for the tip on the other VR! i...

Hello all, Does anyone have any experience manipulating the trimmer resistors on these amp boards? here is a link to one: https://stores.goldeneagleradios.com/rci-x9-amp-board-with-hardware-feedback-no-warranty/ there is a VR near the input/output section, and another on the opposite end near...

I have found that the Noise Blankers in the 858 SSB chassis have a night and day difference in performance between when they are aligned with a signal generator set a 23.5mhz as opposed to being tuned by ear. both methods will get you noise blanking, but they really shine when they are done...

Hi OT03, I apologize if there was any confusion, i was asking you to send me a private message here on the forum so we could exchange information. I'll send you an email tonight. LC

There is a very famous chart that became popular quite a few years ago that people like to use for making CMC's by winding coax. its the one with all the green, red, and yellow. the guy who made it had a foreign call sign, something like GTX... or something like that. the thing about this...

save yourself a world of headaches and get a set of these: https://www.ebay.com/itm/203312251989?mkcid=1&mkrid=711-53200-19255-0&siteid=0&campid=5336136228&customid=&toolid=10001&mkevt=1 no need to remove any connections or coil any cable. LC

maybe a bit off topic since this is not a butane soldering iron, but if anyone wants a great tool to use for soldering PL-259 connectors, get one of these: https://www.amazon.com/Weller-120V-Soldering-Iron-Power/dp/B0962NM5PD/?tag=worradfor-20 grind a small curve into the tip so it will sit...

yeah this should work just fine for you. yes, the selector worked fine and turns nicely. I used to put a lot of digimax kits in madisons for people so i have a stash of these. I don't care about the money, just give me enough to ship it to you in a small flat rate box. you can shoot me a...

just how much of the channel selector do you need? I have a couple from madisons i converted to encoders, but i don't think the flimsy plastic with the traces will work for you. but if you just want the selector itself i have one for you. LC

no they are just like this these days. While im happy that people are having meters made that fit our radios, i do wish they were a bit better made. Ive seen this with replacement 2000GTL meters, 142GTL style meters, as well as the galaxy and ranger meters. LC

you are getting good advice here, but just to answer your initial question; you have a dual final radio, meaning that out of the box the deadkey on AM would be around 8 watts. That's too much for a 2 pill amp and depending on how a particular 4 pill is set up, it could be too much deadkey for...
