|Being a bit long in the tooth, I am trying to get my flex 3000 to talk to my MFJ998 atu via the I2C flex data bus. Is there anyone out there who has managed to get these two talking to each other.
I did get a breakout pcb for I2C to usb, but realize its all over my head. I am looking for a solution please.

|ok, so this is not good as I don't want to change those devices for one's with a higher drain voltage. Are there any resources where I can read up on this subject, related to mosfet devices. Looking through some books, its looks as if I will have to modulate the driver as well.

|I have an old "chatterbox transceiver" solid state and am looking for advice on how to connect an AM modulator to the small amp pcb with 20w output. The am uses a pair of RD15HVF1 devices. I was think along the lines of using a small audio transformer with a centre tap secondary connected to the supply voltage and the other end "floating". The centre tap will connect to the modulator cao an electrolytic cap. The primary side connects to the mic and gnd. Has anyone got any tips or ideas on other types of ways of getting AM audio into these devices.

|Hallo all, I am not sure where to place this, but here goes. I have got what I believe is to be a signed person copy of the 1926 1st edition of the radio amateurs handbook softbound. Its has a signature of F.E Handy - personal copy inside the 1st page. Its in near mint condition and comes from an estate sale or sk sale.
I would like to find out if this is the genuine signature and a genuine copy of the handbook, which might be worth a lot of money to someone.
Can anyone help ?

|Hi, Well I have tried endlessly to get it working with programs like cw skimmer, faros, fldigi and wspr/wsjt. Before I go further, let me say that I have a medical problem due to getting chickenpox aged 45 and struggle with rubbing two pennies together in sync...hi
I purchased a copy of VAC software and need someone to help me perhaps via skype to set this all up. Concentration is my worst enemy. If anyone can help my sky id is m0els-uk
