would like to do it for free, we just can't. We have a flat fee of $30 plus parts to repair a tuner (most

resistors and capacitors are included in that fee). The 68HC11 chip is the most expensive at $20. Relays are

$5 each. The 34064 is $5. The 78L05 is $1.

We will not attempt to repair any unit that has been soldered with acid core. We reserve the right to

refuse repair due to excessive problems or damage due to construction.

Before any unit is sent to us, you must first call to get return authorization (just so we know your unit

is on it’s way). All units sent in must be prepaid, either by check, money order or Credit Card unless

otherwise indicated. Package unit carefully and keep in mind we will use your packaging to return the unit

back to you. Include a description of what problem you are having and a phone number you can be reached at in

the evenings in case we have questions. Repairs average about 3 to 6 weeks, depending on the particular

problem.

Upgrades:

  We are continually trying to put more features in the software of the tuner. The current

version  of the software (QRP 1.0) was locked in with only 4 bytes (out of 512) of code space left.

If you have an idea of how the unit can be made better (in software or hardware), please send a

description of your upgrade. If we use it for the tuner, we'll send you a free upgrade. We can mention now that

we do not have enough code space to implement tuning from memory or adding an LCD display (but we're

working on it). Future upgrades will be available for about $10 with 68HC11 chip trade in. If you purchased

the kit from LDG, we will notify you when upgrades are available. If you did not purchase the unit from LDG

and you want to be on our mailing list, just drop us a card, letter, fax or e-mail.

Feedback:

We encourage everyone who builds the kit to drop us a note (card, letter or e-mail preferred)

to let us know how well it works for you in your particular installation. This will ensure that we have

provided everyone with the best tuner kit possible and we can maintain a database of how well the tuner

performs.
