Therein lies a problem; I had considered the use of 270MHz
SAW filters as used in GSM phones as RX roofing filters, but with the deign of GSM phones moving en masse to direct conversion, that's not possible. One area in which we can assure some degree of future proofing is to define the interfaces between the sections so that any section could be replaced by circuitry of your own making and/or of your own repair.

Dear Airy,
I can't resist the temptation to read most of what you write. It's habit forming. It's because there appears to be an unexpected element of truth in many of your thought-out if unruly statements. But try not to be so offensive in your, chip-on-the-shoulder, mode of expression. You could be even more effective. ---- Reg. |

Dear Reg,
Thank-you for your few kind words. I, in my turn, read with interest your contributions to the various NG. From what you profess, I have much to learn about the common sense of what really happens in antennae and feeders and I am an avid pupil of yours. (That is part of parcel of Ham Radio, not only to improve one's own knowledge, but also to encourage others in what is essentially a technical pursuit.) As to offensiveness, none is intended. If it was your intention to refer to my stance against the gangrenous degeneration that is the M3/CB Fools' Licence scheme, then I regret that I can offer you no apology. We Radio Hams must take a stand now, and that stand must be to refuse to have anything to do with what are essentially second-class citizens in the radio context. In other matters, if you do indeed refer to other matters, I speak my mind and I speak the truth as I see it. Do not be so surprised at candidness and openness. (If there are those who take the liberty of taking offence at ideas expressed that are not their own ideas, then they would be well advised not to read an international forum such as this NG. Caveat Lector. "Reg Edwards" wrote in message ... Dear Airy, I can't resist the temptation to read most of what you write. It's habit forming.
