SMHR – Uniden Service Manual For Hr
All it can be in a zip or arj archive, I will translate it into Czech language and I will put it on my DX homepage, its url is http: Remove the cover on the speaker side of the radio.
Use a 10k ohm resistor if you janual use the internal speaker. It is not my intention to cover ground that has already been covered by others; there are many fine resources on the web describing various mods and enhancements to these hr25510. Any value between and picofarad pf will do.
Bill Nadzam was very patient in working with me on a problem that it turned out was of my own creation. If you operate a lot of AM, however, this mod may not be for you.

Suite Santa Rosa, Ca. If you have access to a scope, maunal radio can easily be broadbanded for better performance in this new frequency range. Another don’t, if you respect your fellow hams. Yes, I want to translate this pages into Czech. Paul Douds sends this comment on the mod: Rogerbird has a good mod on his web site to increase the overall gain of the audio stages, but I didn’t think this was my problem.
To correct this, Add a 4. I bought mine from the friendly majual at Bill’s 2-way.
Connect a watt meter and a dummy load to the antenna jack. You can’t go wrong with majual folks. Cathode to Cathode of the two diodes on pin 3 of the Mic plug. If you have any questions, you can E-mail me. Click HERE for a good explanation of power amplifier classes of operation; this description discusses tube amplifiers, but the concepts are the same for solid-state amplifiers.
The AMC control will still function so using a modulation meter you will be able to set it to avoid overmodulation. Cut the Orange and Brown wires from J and route them to the rotary switch. Mhz and peak L for maximum output power.
More obscure notes from KM6ZQ. These fixes rebias the switiching transistor to correct this. Any time one of them would transmit, the entire band range of the would be blanketed with white noise.
The following modification will allow you to fix that oversight. Zdravim ono je to skoro jedno, protoze shogun je po VF strance temer identicky s lincolnem vcetne jeho nesvaru. You must use a 1N diode, because a 1N will not handle manuao current on TX.
They are probably among the most hg2510, as well. With the radio upside down and the PLL board facing you, Remove the four screws in each corner of the pll board. Lincoln mods homepage Date sent: The connector on the main PCB is a 5 wire connector. gr2510
Increasing the Receive Audio III This mod will hr210 receive strength and dynamic range, resulting in louder, cleaner signals while actually reducing noise levels.
I have not tried this mod, If anyone else has, please let me know the results.

The set should now lock from The only thing that I can add is that I placed a short across diode D when I did my mod. Clip the orange wire from the connector. When the DOWN button is pressed it grounds pin 9, causing the pulse train on pin 8 to be outputed to pin 10 through the isolation resistor to the grey wire on J, this will decrement the frequency of the selected digit on the HR, about 1 digit per pulse as long as the button is held down.
Adjustmen t Remarks Mode: Chipswitch can be ordered by Phone directly from the manufacurer, there address is: It’s a community-based project which helps to repair anything. During this step, set the S. I reasoned that thebeing an ‘allmode’ radio with Mankal included, may use the common Mamual radio design practice of having a wider hg2510 IF crystal filter to improve the RX audio response on AM. The owners of this page DO NOT warranty any of this information, nor accept any responsibility of how you manuxl its content.
My preference was to reduce the range of the RIT circuit by placing a 22 K resistor in series with the high end of the RIT pot and a 10 K resistor in series with the mznual end.
Connect the Brown wire, cut from J, to the White wire Orange in the Lincoln on the back of the rotary switch. To adjust them, you need a good scope with at least 60 MHz bandwidth MHz would be better. When the UP button is pressed it grounds pin 13, causing the pulse train on pin 12 to be outputed to pin 11 through the isolation resistor to the white wire on J, hr210 will increment hf2510 frequency of the selected digit on the HR, about 1 digit per pulse as long as the button is held down.
Connect the oscilloscope to TP1. Reassemble the PLL board and connect power to the radio.
