I am getting very close on this ole gal. I am noticing on AM may receive is about 3kc lower than it should be. Example, the frequency is 27.305, but to clear it up I have to move the vfo to 27.302, then in crystal mode the clarifier will not get there (about 27.304 or so. It is like this on all...

I have another D201a that had low SSB modulation. I started with setting the bias. I set the AM and LSB bias for -40. LSB R707 trimmer was on the stop to get there. (I found the am set at -8) Then to neutralizing the tube, final tuning etc. This is where it gets a little funky. Down to line 15...

Well here we go again. After the SSB receive is finally working for a day or 2. Now I have lost the AM carrier. However, it will still modulate 20 watts. I have 0 power/modulation on LSB or USB. Before this happened AM transmit worked good. I had a 5 watt carrier on am and 20 watts modulation. I...

I received a Varmint XL1000 from a SK about 3 years ago. It has been sitting ever since. I pulled the covers off last week and the power supply board is mostly unhooked. I have no idea where these wires go. I have searched (with no luck) for a schematic for this. If anyone has one they are...

I have an circuit board D201 with a BM board number of 17020-0 on the circuit board. I have a couple spare BM boards from late model D201As. The number on them are 17029-A, this board it a little wider on the filter side than the old one. Just the space past the pins are wider, it will plug in...

Hello, i have a late production D201A. with very low mileage. The resistors are not toast, the BA board looks new, very little darkness on the inside of the top cover. Hey get this, it has a perfectly smooooth and working BLACK channel selector. I did take it apart to clean and lubricate it, and...

I have put the old d201 aside and have the D201A on the bench. I had to replace a tube socket and a crystal on the synth board. Anyway I was checking it out today and noticed I had no RX on the manual side. I did have on the crystal side, but it wasnt the best. I noticed on the man side it just...

Hello, I have a D201 that I am recapping and going to put in new resistors. The 100K tuneup as Nomad calls it. I have most of the electrolytic caps replaced. I have realized that I did not get the yellow caps located on the boards. I think they are .22mfd, 250v and appear to be paper. I cant...

Hello, I have a jb150 that has higher than I like swr on the input side. This is between the radio and jb150. When it is out of line I have a 1.1. When I put it in line it is around 2.0 - 2.5. I have done the normal things like changed jumpers 3x etc. I dont have to turn on the jb, just have it...

hello, i have a rs-10a astron that i received not working. i have tried to get it going but have had no luck. i will list the things i have done. maybe i missed something simple. first off i have 28v on the large cap screws, also have 29v on the input for the 723, pin 12 i think. i found...

Hello, I have a yaesu FT101EE late model 25001+ serial. No rx, and very little tx, maybe 1 watt. I suspect tubes on the tx. First I want to tackle the rx. I have no noise or static on internal speaker, external speaker, and headphones on any band or mode. Absolutley nothing at all. This...

hello, i just replaced the final in this rig. i was looking for the info on setting the driver and finals bias. anyone know the procedure, and voltage? thanks and happy new year oops...i forgot to say i put a 2sc2879 in, because i had no 2sc2290, thanks

hello, i have some questions about this pair. i got a set of these the other day with no relay in the transmitter, completely missing. i was hoping someone would know the replacement number for this or a substitute number. i have found replacements for about 30-40 bucks, but i have a box of...

hello, i have another president 2510. this one receives good, has about a 7w carrier, but no modulation. i have checked the obvious like the mic. i have another one mobile and it works fine, so its not the mic. i also have replaced the 2 capacitors that usually cause the no mod problem c95 and...

ok i built another antenna......scary huh? anyway, its a 5/8 wave vertical with 3 ground radials, i have tried it with 4 also. i used the tuning ring method for matching. the swr is a perfect 1.0.1 using my mfj analyser, rs=52 xs=1 or 2. when i add power it jumps up over 2. i have tried...

hello, i have a kenwood th-78a that has a small problem. the vhf side squelch stays open no matter where the knob is at. the green light stays on and full bars on the meter. there is no sound coming out of the speaker. this is only on the vhf side. i can use the uhf side fine, also can change...

i bought a tram d201 23 channel. it looks great and worked great with outstanding receive and transmit. i have had it a month or so now. i hooked it up last night and talked on it and got great audio reports as always. anyway i got busy doing paperwork and was just letting it sit there and...

hello, i just bought a great looking drake l4b. i was hoping for some pointers on setting it up (tune and load). also what kind of power should i see from this am and ssb? also how should i drive it (how much wattage)? if anyone has a place to download a users manual too it would help. i got...

well i heard a guy here locally had a heathkit sb-220 for sale with 2 3-500z tubes in it. first off the bat he said it would do 3500+ with 300 drive in AM mode. hmmmm got me to thinking. is this possible? maybe so...i dont know. he did say it was set up for am and 11 meter. not that i have...

hello, a friend has bought a new connex 4300hp. i was needing the conversion and peak and tune for him. i was thinking its the same as the 3300, but there is no number on the board. so i thought i would ask here first, before i told him how to do it. thanks very much guys
