To: ham-equip@ucsd.edu A transistor in my FT736R power supply literally burned up. The set of schematics for the FT736R does not include an schematic for the power supply so I cannot identify the part. I don't have a service manual, which I assume may have a schematic. Therefore, I was wondering if anyone who has such a diagram could help me identify the part. On the power supply printed circuit board the transister is marked as Q3. It's emitter is connected to a diode and its base is connected to two 33 ohm resistors. Unfortunately, I left my notes about this at home, but I believe the diode is marked as D8 and the two resistors are marked R16 and R17 (or R17 and R18). Anyway, I believe this information should help pinpoint the transister on a schematic. There is probably some other bad component on the board (one that caused the transistor to go out) but I will deal with that problem. Thanks, Dick.

To: ham-equip@ucsd.edu The BayPac (BayCom) modem was fun, but, it is time to upgrade to a REAL TNC. Most of my packet operation is in TCP/IP but some is still AX-25. All of it is in VHF/UHF (HF privs yes, radios no). The option of operating "portable" is attractive for coolness and/or emergencies, but, is not essential. I am trying to decide between asking for a PK-88, KPC-3 or DPK-2. Some of the relative merits that I know of include: PK-88: Y Y N Y ? ? $139.95 KPC-3: L 1 Y Y Y Y $119.95 DPK-2: L Y N Y 2 3 $109.95 ^ ^ ^ ^ ^ ^ ^ | | | | | | | | | | | | | +------- HRO Price | | | | | | | | | | | +--------- Open squelch operation | | | | +------------ TNC-2 Compatible | | | +--------------- PBBS | | +------------------ WEFAX | +--------------------- Kiss Mode +------------------------ 12 Operation (L = Low power consumption) 1) The guy at HRO said it does KISS Mode but it didn't say in the catalog. 2) "100% firmware compatability with TAPR TNC-2" "* TNC-2 Compatible * Runs all TNC-2proms" 3) $31.95 optional board Oddly enough, the guy from HRO didn't talk up the DPK-2 at all. He said the other two would work fine but that if I wanted to do HF packet some day then I should not get the KPC-3.

(C228A) To: ham-equip@ucsd.edu Howdy.. I'm in the market for a dual band HT (possibly) and I'm most interested in getting one that's 2m/220. The only one I've seen so far is the Standard C228A. Does anyone have any recomendations on Standard radio equipment? They seem to be pricier than the usual Alinco and Yaesu group, so is there a reason for this?

I tried this, I also tried the reset given in the manual, and also tried each button separatly during power on, none of them unlocked the radio. I found out later from Al (legerlotz@smaug.enet.dec.com) that you can get it out of this locked up state by removing the TSU-7 or disassembling the radio. --GaryM ------------------------------ Date: 29 Nov 1993 16:49:17 GMT From: tymix.Tymnet.COM!drawson@uunet.uu.net To: ham-equip@ucsd.edu References <2cjdqg$6vd@tymix.Tymnet.COM>, <CGwsFq.LHq@bigtop.dr.att.com>, <931126.39454.PEITZER@delphi.com> Subject : Re: Kenwood 940 PLL Unlock problem I fixed it over the week end, I think! Resistor R100 on the PLL board was making intermittent contact on the end closest to the circuit board. (R100 stands on end.) I was able to clip the other lead and solder a replacement resistor on the component side without exposing the solder side of the board. (It would have been tedious to get to the solder side of the board.) I was INTENDING only to tweak up the three coils (L22, L23, and L24, I think) that Kenwood specifies in Service Bulletin 900. I put a 'scope on test point TP4, and tried to peak those coils. There were already nearly right on. But the trace jittered. I let things sit that way, with the scope still connected, and eventually the PLL unlocked. Without mentioning all the things I checked, and lines traced in the schematic, that didn't pan out ... eventually I reduced the scope's gain and switched to DC coupling. When the PLL unlocked, the trace went to zero volts DC, as well as showing no RF signal. Even LATER (!) I noticed that by nudging the bottom of R100 very softly with the the nylon alignment tool I could cause the PLL to cut in and out. It turns out that test point TP4, on the bare lead of R95, connects to R100, which connects to the DC supply voltage to the stage. When the R100 connection opens, TP4 (and the stage) is disconnected from the DC supply. I did not determine whether the intermittent connection was inside the resistor or between the resistor's lead and the solder trace. I couldn't simply pull the resistor off the board (or pull it apart) once I clipped the top lead. And there was not enough mechanical play for me to notice any sound or feeling when I jiggled the resistor. But I doubt that the fault is specific to the PLL circuit at R100 -- it probably could have happened anywhere in the radio. I'm glad it happend right where Service Bulleting 900 happened to direct my attention (and scope probe). 73, Dick ------------------------------ End of Ham-Equip Digest V93 #117 ****************************** ******************************
